Before the beginning construction work Any owner of land on which it is planned to build a residential building wants to know how much material will be required. Financial costs will depend on the volume of building materials and their type, which can be difficult for some owners to bear at one time, and they are forced to purchase various materials step by step. In low-rise housing construction, wood and products made from it make up a significant part. Therefore, it is advisable to know how many boards will be needed and how much they will cost.
Thanks to the accurate calculation of the number of boards, you can save a lot and not be deceived
Characteristics of wood materials
Currently, the building materials market offers various wood materials at a price in rubles per cubic meter. If it is known how many boards will be needed for arranging the floor, I would like to know their price. In addition, construction requires different types of wooden products, differing in shape, size and price. Therefore, before studying the question of how many boards are in a cube, it is necessary to study the range of offered wooden products. To build your future home, the future homeowner may need:
- profiled timber square or rectangular section, the smaller side of which exceeds 100.0 millimeters;
- a block whose dimensions are:
- ü 16.0…75.0 millimeters for sawn wood products coniferous species;
- ü 19.0…100.0 millimeters for hardwood.
- edged board, processed in three planes, with a thickness of more than 20.0 millimeters, the width of which varies widely;
- unedged board having two sawn sides, the side edges of which are unprocessed;
- croaker, which is lumber half sawn from round timber ;
- terrace board http://www.ecowood.com.ua/catalog/terrasnaya-doska for flooring.
The greatest financial costs will be required for the purchase of the first three types of lumber, so solving the question of how many timber, whetstones or boards are in a cube is most relevant.
Accurate calculation of the amount of lumber in one cubic meter (1 m³)
The task of determining how many boards are in a cube is at the level of arithmetic tasks solved in the first grade. The initial data for calculating how many timber, bars or boards are in a cube are:
- z – number of boards (pieces);
- h – thickness of the board (smaller sectional size of the bar) in meters;
- b – width of lumber (meters)
- L – length of a unit of lumber (meters).
The volume (V) of one product (board, beam or bar) is determined by the ratio:
V = h×b×L, cubic meters,
and the number of units of lumber in cubic meter let's define it as:
Of course, this calculation is quite approximate - it does not take into account the gap between individual products, the type of board processing (grooved, planed), length allowance and other rather specific details. Using the above formulas it is impossible to calculate the amount of edged boards or croaker. However, to determine what amount to take with you to the lumber yard, and whether an extra thousand rubles would be a problem there, accuracy is sufficient. More accurate results can be obtained using the tabular calculation method.
Tabular determination of the amount of lumber
To determine how many boards are in 1 cube, the calculation table contains columns and rows. The lines indicate the cross-section of the lumber, and the columns (rows) show the calculated values of the volume of one board and the number of boards in one cubic meter. In principle, these values are obtained by calculation, but taking into account correction factors. Let's consider a cutting (part) of the table of how many boards are in 1 cube. Wherein symbols correspond to those used in the above formulas.

When constructing a cottage or house, the master, by necessity, performs a lot various tasks. He thinks through all the construction processes and draws up the necessary estimates for each of them. Calculate the correct quantity necessary materials not easy. This requires knowledge of mathematics. He must know: how many boards are in 1 cube, how many, and so on. If he has such knowledge, then that’s great! He is a real master!
But for an ignorant person, “how many boards are in a cube” is an abstract concept. In order for him to understand it, he should know exactly what building materials made of wood are. What are they, how are they measured? Without knowing this, he will not be able to adapt to these calculations.
Edged or tongue-and-groove, as well as other types of lumber
The first thing you need to understand is that it is not so important from which forest exactly this or that material was made. The boards may not be the same, but their calculations will be completely identical. Let them have different varieties, various sizes, the calculation is still carried out according to the same principle. It's still wood and will be measured the same way! It can only determine how many boards there are in 1 cube will be different each time. Regardless of whether it is edged or tongue-and-groove, cylindered, etc. the calculation will be the same.
Non-grooved lumber- different timber, edged materials, their non-edged counterparts, this is the case when their cubic capacity is calculated completely differently! These products have grooves and tenons. They are intended for joining between forest units. Such products include:
- blockhouses;
- floor material;
- imitation of various timber.
When purchasing such a grooved one, you should take into account the circumstance. When calculating cubic capacity, you need to take only the working width of the beam. The spike is not taken into account here. And when calculating the cubic capacity of a blockhouse, which can imitate a log, one should take into account its thickness, which it has at its highest point.
Examples of calculations using formulas for the volume of 1 m3 of timber, as well as price comparison
Any specialist has known since school exactly how to calculate the cubic capacity or how many boards are in 1 cube. To do this, you need to find the product of 3 quantities: height, length, width. The same method is used to calculate the cubic capacity of a unit. When making calculations, it is more convenient to immediately convert the parameters into the value “Meter”.
For example, the cubic capacity of a unit of material having a length of 6 m and a cross-section of 150x25 is calculated as follows: 0.15 m x 0.025 m x 6 m;
The formula we will calculate is this: V= L*h*b (where L – length, h – height, b – width)
The calculation results in 0.0225 m3. This is the cubic capacity of one product. If you want to know the cost, then 0.0225 must be multiplied by the cost of 1 cubic meter. After calculations, it turns out that if we miss it, the cube will cost 6,500 rubles. And the price of one of them will be 146 rubles. 25 kopecks Here, for the ignorant people, lies a little trick of the sellers.
Typically, cubic capacity can be rounded to 0.023. This means that lumber will cost the buyer 149 rubles. 50 kopecks Sometimes unscrupulous sellers can round up a cubic capacity with a size of 150x50 mm to approximately 0.05 m3. But if all calculations are performed correctly from the very beginning, it turns out that with correct calculation the result is only 0.045 m3.
It seems, so what, someone will say! The numbers are small, but the result is stunning! Such rounding will involuntarily lead only to the fact that the unit price will already be 325 rubles. instead of 292 rub. 50 kopecks And these calculations are carried out taking into account that the price of a cube is 6,500 rubles.
In addition, you also need to know and take into account that boards with a nominal length of 6 m actually have a length of 6.1-6.2 m. This should not be taken into account when selling lumber! Sometimes customers may ask to know how many boards are in a cube. This applies to acquisition more boards
Everything can be clearly seen from the example of purchasing boards with dimensions of 150x25 mm, where their number in a cube is 44.4. But still, most often only 44 boards are considered a cube. And if calculated correctly, this amount is listed as 0.99 m3. In reality, it turns out to be an overpayment for 1 cubic meter. It is approximately 1% of its initial cost. It will look like this: what instead of 6435 rub. for 1 cubic meter the cost will be 6,500 rubles.
The volume of unedged timber is calculated in a completely different way. If you buy one of them, then measure its thickness and length as accurately as with edged lumber. But its width is taken as average. That is, it is between the smallest and the largest. Example: at one end its width is 30 cm, and at the other about 15 cm, then to calculate the cubic capacity this parameter will be 22-23 cm.
If you need to find out the volumes of a large number of timber or determine how many boards there will be in volume, they should be laid out in stacks. But so that the widest of them does not differ from the narrowest by more than 10 cm. In such a stack, their length should be the same. But this is only approximately! After this, you need to use a tape measure to measure the height of the stack and its width. These measurements are taken somewhere in the middle, the same applies to length.
The resulting calculation result should be multiplied by a coefficient. It ranges from 0.07 to 0.09. It depends on the air gap, which is between the material. When performing calculations, the larger the gap, the lower the coefficient taken. If it has the same dimensions, then you can determine the number of boards in the cube.
By the way, for such calculations there are special tables in builders’ textbooks. Similar tables exist for almost all lumber starting from and ending with. They indicate the cubic capacity of common types of timber or other types. And calculating the volume of boards, for example, for a fence, is not difficult! You can use the above formula yourself!

Video on calculating lumber in a cube using formulas and tables
When carrying out construction work on the construction of a residential building, a specialist must perform a large number of different tasks, some of which are: drawing up and calculating estimated cost before the final finishing of the premises of a residential building. It is mandatory to calculate the required amount of various building materials, which is quite difficult to do. Therefore, such knowledge - how many boards are in a cube - has a very important for a specialist who is engaged in the construction of a residential building and wants to complete the work as efficiently and quickly as possible.
Buying club: existing types of boards
To calculate exactly how many board pieces are in a cube, you will need to know not only what exactly a board cube means, but it is worth understanding important point that there are different types of boards and what is possible to purchase on the modern market for performing a variety of construction work. It should be noted that the cube of almost all materials, regardless of the type of material, is calculated in the same way, that is, according to one specific method. The types of boards have no influence on the calculation of the cubic capacity of this building material.
Non-grooved types of lumber are: timber, various edged boards, as well as unedged boards (they are an exception when calculating cubic capacity, because this process occurs a little differently). Tongue-and-groove types (which have special grooves for making joints) include: modern lining, blockhouse, flooring material, as well as imitation of natural timber. When you choose a tongue-and-groove type of building material for purchase, then you will need to pay attention to the fact that when making calculations, only the working width of the board without a tenon is used. If we talk about a blockhouse (imitation log), then when calculating the cubic capacity, only the thickness at its highest point is taken.
How many boards are in 1 cube: performing the calculation
Any person, even from his school days, understands how cubic capacity is calculated. For this procedure, it is necessary to calculate quantities such as: length, width and height. A similar principle is used to calculate the cubic capacity of 1 board. When performing such calculations, it is recommended to convert all available values into meters. The cubic capacity of 1 board, which has a cross-section of 150x20 mm. and a length of 6 m, is calculated as follows: 0.15 multiplied by 0.02 and 6, so that the cubic capacity of this board will be 0.018 cubic meters.
Let's apply the volume formula V= L*h*b (where L is length, h is height, b is width).
L= 6.0; h= 0.02; b= 0.15.
Thus, V= 6.0*0.02*0.15 = 0.018 m3.
To determine how many boards are in one cube: divide 1 m3 by cubic capacity (the volume of one board).
1 m 3 / V = N pcs.
1 m 3 / 0.018 m 3 = 55.55 pcs.
Thus, the number of boards in one cube is 55.5 pieces.
Finding out the cost of a certain type of board when the values of its volume is known is quite easy: 0.018 multiplied by the price of 1 cubic meter. When 1 cube of a certain type of board costs, for example, 5,500 rubles, then the cost will be 99 rubles. At this moment of calculation, there is some trick of sellers and managers in construction stores, because the cubic capacity of the material is rounded to some integer values.
Such rounding can lead to such a moment that the price of 1 board (when 1 cube costs 5500) will be completely different values. In addition to all this, it should be noted that various boards for construction, which have a nominal length of 6 meters, actually have a length of 6.1 - 6.2 m, which is not taken into account when selling this building material. This also applies to the purchase of a significant number of boards. This can be seen quite clearly if we use a 150x20 mm board as an example. The number of boards in a cube is a value of 55.5 pcs. But, in a cube they count 55 pieces, which when performing the calculation will have a value of 0.99 cubic meters. In fact, it follows from this that the overpayment for 1 cubic meter of this popular building material can amount to 1% of the real price. For example, 5500 instead of 4995 rubles.
To calculate the cubic capacity for a continuous type of board, slightly different methods are used. When we are talking about buying 1 board, then measuring its thickness, as well as the total length, is carried out in the same way as when choosing edged building material. In this case, the average width is taken for calculations - between great value and small.
For example, when the width of the board at one end is 25 cm, and at the other 20, then the average value will be approximately 22 centimeters. When it is necessary to calculate the volume of a significant number of similar boards for construction, then you will need to lay them out so that the wide one does not differ from the narrow one, more than 10 cm. The main length of this material in the laid out stack should be approximately the same. After this, using a regular roulette, precise measurement the height of the entire existing stack of boards, the width is measured (approximately in the very middle). The result obtained will then need to be multiplied by a special coefficient, amounting to a value from 0.07 to 0.09, directly dependent on the existing air gap.
How many boards are in 1 cube: special tables
To calculate the exact number of boards of a certain width and length in 1 cubic meter, various tables are used. Below are several such specialized tables, which indicate the cubic capacity of the common and in demand types of this material today. It is possible to calculate the volume of various boards of different sizes, for example, material for erecting a fence on your site, using the existing formula presented above.

Table of the amount of unedged boards in 1 cubic meter
We will send the material to you by e-mail
When starting construction, any House master one day he is faced with the need to purchase boards. And this is where the fun begins. Having calculated the required quadrature by width and length, the beginner grabs his head - what to do? After all, such material construction markets Sold by volume, not by area. Today we will try to figure out how many boards are in a cube (a table of average values will also be provided by us) and how to make all the calculations ourselves. Also at the end of the article there will be an online calculator that will allow you to perform all the necessary calculations without any problems.
It is important to know not only the size of the lumber, but also its volume
Everyone understands that the shape and size of the lumber will determine how many cubic meters will be needed for a particular construction. But first you need to understand what types and types of material can be found. The main ones can be identified:
- Edged timber;
- Planed timber;
- Planed block;
- Edged block;
- Edged and floor boards;
- Unedged materials.
Each of these types has its own characteristics and is used in its own area. For example, there is no way to build a frame without it, but covering a wall with it is the height of irrationality. To do this, we will now consider each of these types separately.
Edged timber and its areas of application
Edged timber is used in cases where aesthetics are not so important in appearance. It may have cracks that appear during the drying process after processing. It is made by sawing out the central part from an ordinary log, and only after that it undergoes minimal drying. Although such lumber is considered expensive, it is still cheaper than planed products.
Planed timber: what is its difference from edged timber
The differences here are fundamental. If for the production of the previous version no preparation of the log is required, then for planed it is first dried, and only after that it goes to the sawmill. The surface of this product is smooth and polished. This type of timber can even become a good decorative element. Simply put, if it is necessary to erect walls for finishing, purchase edged timber, but planed does not require finishing. It can simply be varnished. If we talk about strength, it is less for a planed product.
Planed timber - what is its difference from timber
At their core, these are the same thing, the only difference is in size. The block has a lower rib height, which means it is not suitable for constructing building frames or residential buildings. More often this material is used for decorative purposes. It also finds application in the installation of frames for interior decoration or reinforcing lintels of various wooden panels. The difference between edged and planed timber and the same types of timber is the same.
Edged and floorboards: their features and differences
The differences between these lumber are also noticeable at first glance. The edged board is not planed. It has an even shape but, at the same time, is in no way suitable for finishing. In contrast, the floor has three smoothly processed edges (except for the lower wide one) and often has a groove on one side and a tenon on the other on the narrow sides. This is done to connect them more tightly to each other, as well as to reduce loads and eliminate deformation of the floor during operation.
Unedged materials - what are they?
These are the cheapest products. When sawing a log, only two opposite sides are processed. Thus, the edges of the boards are uneven. More often, such lumber is used for rough construction.
How many boards per cubic meter: table of standard sizes
Some people ask an interesting question - how much? square meters cubed. In fact, it is impossible to answer it! After all, in order to determine this, you need to at least know the thickness of the board. Without this parameter, no calculations will be possible. Let's try to understand how to calculate cubic capacity.
This does not present any great difficulties, but it requires care. We need to understand how many boards are in a cube. And to do this you need to calculate the cubic capacity of one of them by size. For example, a board with a cross-section of 1000x250 mm and a length of 4 m. Then the calculations, after converting the units of measurement into meters, will be as follows: 0.1 × 0.025 × 4 = 0.01 m 3. This will be the answer to the question of how to calculate the cubic capacity of the board.
How many boards are in a cube: table of average values
For example, there are boards with certain sizes. How to calculate a cube of such lumber by the number of boards? You can use the following table:
| Board size, mm | Volume of 1 board, m3 | Number of boards in 1 m3, pcs. | Volume of overpayment when rounded down, % |
|---|---|---|---|
| 25x150x4000 | 0,015 | 66,7 | 1 |
| 40x150x4000 | 0,024 | 41,6 | 0,7 |
| 20x100x6000 | 0,012 | 83,3 | 2,8 |
| 25x100x6000 | 0,15 | 66,7 | 1 |
| 40x100x6000 | 0,024 | 41,6 | 0,7 |
| 50x100x6000 | 0,03 | 33,3 | 1 |
| 25x150x6000 | 0,025 | 44,4 | 1 |
| 30x150x6000 | 0,027 | 37,04 | 0,01 |
| 40x150x6000 | 0,036 | 27,8 | 2,9 |
| 50x150x6000 | 0,045 | 22,2 | 0,9 |
| 25x200x6000 | 0,03 | 33,3 | 1 |
| 40x200x6000 | 0,048 | 20,8 | 3,8 |
| 50x200x6000 | 0,06 | 16,7 | 4,2 |
It is important to know! To calculate how many square meters are in a cubic meter, you need to know all the dimensions of the board. Without information about length, width and thickness, nothing will work.
Average weights at different humidity levels
| Breed name | Crude, kg/m3 | Dry, kg/m3 |
|---|---|---|
| Birch | 880 | 650 |
| Oak | 990 | 720 |
| Spruce | 710 | 450 |
| Cedar | 700 | 440 |
| Larch | 840 | 670 |
| Linden | 750 | 500 |
| Aspen | 750 | 500 |
| Pine | 810 | 510 |
| Ash | 960 | 700 |
It turns out that one cube of ash will be much heavier than the same volume of linden. This should be kept in mind when planning your transportation.
How to correctly calculate the amount of material
Let's look at how to correctly calculate how many pieces of boards there will be in one cubic meter. This is done according to the following formula:
1 m 3 / (L × h × b) = N pieces , Where
- L – length of the board;
- h - width;
- b – thickness.
As you can see, the calculations are not at all complicated.
Helpful information! If they say that an inch board is needed, its size will be as follows: width - 75-250 mm, length - 2000-6000 mm, but the thickness is always standard - 25 mm. This size name can often be heard in construction markets.
Board cubic capacity calculator or how to make calculations easier
The algorithm itself for how to calculate a cubic meter by quantity is probably now clear. But there is not always a desire to study various calculations. And it’s quite easy to make a mistake here. Now we will tell you how to calculate cubeboards without making complex calculations.
For such cases, there are special programs called cubic meter calculators. Why are they convenient? The main advantage of such programs is their accuracy. The calculator for calculating a board in a cube is devoid of the human factor, which eliminates the possibility of errors in the calculation process. Another rather weighty argument in its favor is the speed of calculations. You just need to enter the correct data in the appropriate fields and click on the “calculate” button. Nothing more is required from the user. The online calculator of boards in a cube will instantly give the result by quantity.
High cost and makes you think about them rational use. has always been one of the most expensive. If you actively use it, then it is advisable to find out in advance how many boards are in the cube. A table with reference data will allow you to determine the required value. You can use the board cubic capacity calculator, which allows you to change online geometric parameters and other products, you can calculate the cubic meter yourself. We invite you to familiarize yourself with the most popular types of materials and the features of their calculation.
planed timber
Planed block
The cross-sectional shape may vary. Manufacturers offer bars with a square, rectangular or other cross-sectional shape. Aspect ratio requirements have been established finished product. Their width cannot be twice the thickness. The last linear dimension can reach 100 mm.
Planed products subjected to special processing have a smooth surface. They are widely used in the construction of various appearance which have increased demands. Actively used in industry.
Edged block
Unlike planed edged timber, it does not undergo additional finishing processing. This significantly reduces its cost. Widely used in the construction and installation of structures intended for installation facing material.
Edged board
The thickness of such lumber can reach 100 mm, and the transverse dimensions in this case should be at least twice as large. During the production process, wood is processed from all sides. As a result, it is possible to ensure the necessary geometric accuracy and relative evenness of the surface.
Edged material is used when performing work various types. Especially popular is the inch board, the size of which is numerically equal to 1 inch (25 mm). This thickness is in demand when constructing sheathing, floors and many other surfaces.
How to calculate a cube? It is enough to multiply the linear parameters to find the volume of one product. Then divide one cube by the resulting value. This will allow you to find out how many products will be in a cubic meter. Knowing the required number of products and how many of them are in a cube, it is easy to calculate the order volume.
edged board
Floor board
Designed specifically for the device. It has a width of 85÷140 mm and a thickness of 27÷45 mm. The choice of linear parameters of the product is made taking into account the subsequent operational load. Online calculator boards in a cube will allow you to calculate how much material you need to purchase for the device flooring a certain area.
floorboard
Unedged materials
Unlike edged material, such lumber has a lower cost, since its surface has partially sawn or unsawed edges (wane). Because of this, it is most often used in the manufacture or construction of rough surfaces.
How many boards are in a cube: table with standard sizes
Knowing how many square meters are required, how many boards there will be in a cube, depends on the linear dimensions of the selected material. Using special reference books (cubes), you can find the required quantity from the tables without tedious calculations.
How many boards are in a cubic meter: the table will allow you to find out without calculation
Reference tables contain information data for lumber of various lengths. Before you find out from the table how many boards are in a cubic meter, you should check all the linear parameters, and not just the width and thickness.
The most popular are reference tables for boards with 4 or 6. So, if we talk about how many edged boards measuring 25 by 100 mm will be in a cube, you should definitely check the length. Four-meter ones - 100 pieces, six-meter ones - 66 (66.6). Based on this, it is determined how many cubes of lumber are required.
Advice! If it is difficult to find reference tables, use the cubic meter calculator, which will help you perform the necessary calculation in a fraction of seconds.
Having determined the quantity from the table, it is worth finding out how much a cube of the board weighs. To do this, you need to know the moisture content of the material. To find the answer to the question, you need to multiply the density by the volume, expressed in cubes. The basic procedure for calculating the number of boards per cubic meter
Before moving on to basic calculations and learning how to calculate a cube, you should pay attention to the unit of measurement. For wood, the unit of volume is the cubic meter. Often cubic meters, cubic meters or cubic meters are used as a symbol.
Attention! One cubic meter is numerically equal to the volume of a cube whose edges are 1 meter long.
V = L × h × b , Where
- V – the required volume of the cube, m³;
- L – product length, m;
- h – height/thickness of the material, m;
- b – width, m.
Attention! All linear parameters must be expressed in meters. If dimensions are given in millimeters, to convert to meters each original value should be multiplied by 0.001.
With the same number of square meters, how many products there will be in a cubic meter will depend on the selected thickness. If the height of the material used is large, then according to the calculations in the cube, a smaller value will be obtained. By reducing the thickness of the board, you can increase the number of products purchased.
When determining how many boards are required, it is necessary to take into account the degree of processing of the material, the grade and type of wood that was used for production. For edged and unedged lumber the calculation will be slightly different. The calculation should be adjusted to take into account the usable area.
When calculating how much trimming material is needed, you should:
- Define linear dimensions one board;
- Find the volume of one product;
- Divide 1 (cube) by the volume of one board to understand how much will be in one cube. According to calculations, the result may not be an integer value.
To find out how much you need unedged boards, measurements need to be taken at several points. After this, the desired linear size is averaged, and the found value is subsequently used when performing calculations.
If there are a lot of boards and their linear dimensions differ, when starting calculations, sort by length and width. It is desirable that the linear parameters differ by a maximum of 10 cm. Then the height and length of the formed stack are measured. The height is measured in the middle. The result obtained is multiplied by correction factor, the numerical value of which is 0.07÷0.09 units. Its meaning can be found in the cubature reference book.
