Repair and construction work often involves the use of lumber. But shops and timber trading centers often sell them not in pieces, but in cubes.
Everything is very simple and fast.
Method for calculating edged lumber
- a caliper, tape measure or folding m; if the length parameters of wood products are known, you can limit yourself to a regular ruler;
- calculator - suitable mobile phone, smartphone, if problems may arise with mental arithmetic;
- a piece of paper and a pencil - to record the results of calculations, how many boards are in a cube.
- Volume = Length × Height (product thickness) × Width.
To prevent confusion when converting cubic centimeters to cubic meters, it is more convenient to immediately record the measurement results in meters.
For example, 0.132 cu. m = 6 m × 0.022 m (2.2 cm) × 0.10 m (10 cm).
Now, to determine the number of planks in a cube, you need 1 cubic meter. m divided by 0.132. The result obtained (7, 5757) when purchasing timber must be rounded to 8 pieces.
This method of calculating cubic capacity is also suitable for timber. This way you can determine how many cubic meters of timber you need to purchase if you know the required number of products, or, conversely, determine required quantity cubes

How to calculate the cube of an unedged board?
To determine the required volume of timber, the easiest way is to carry out calculations similar to the above method. Only the final result needs to be multiplied by 1.2 - correction factor. From unedged boards you can get no more than 70-80% of edged ones.
The width and thickness of each product are measured taking into account its further processing. The technique will help determine the number of cubes wooden products, necessary for work, if the final result is planned for their further processing - pruning.
When purchasing, the widest and thinnest boards are measured to obtain an average width. If the width of the lumber at the butt is wider than at the top, the arithmetic mean of their dimensions is used without taking into account the bast layer or bark, rounded to 10 mm. In this case, fractions from 5 mm are rounded to the full 10 mm, and fractions up to 5 mm are not taken into account. The length and thickness of the lumber are measured in the usual way. The volume of timber is determined according to the usual scheme:
- the volume of one product is calculated;
- the total cubic capacity of purchased timber is determined; according to GOST, correction factors are used: 0.96 – for lumber from coniferous species, 0.95 – for lumber from hardwood wood
In addition to the piecemeal method of determining volume unedged lumber, the geometric method can be used.
Requirements for a package of unedged timber:
- lumber is laid tightly, without overlaps, in horizontal rows;
- on one side the ends of the boards are aligned;
- all sides of the package are strictly vertical: according to GOST, the displacement of individual products outward and inward should not exceed 0.10 m;
- The package of lumber must be the same width along its entire length.
Then the volume of the package is calculated, the resulting result is multiplied by the coefficient:
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 structures, the appearance of which is subject to increased demands. Actively used in industry.
Edged block
Unlike planed edged timber ok 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 much is required square meters 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 reference tables are difficult to find, use a calculator cubic meters, which will help you perform the necessary calculations 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 have 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 obtained result is multiplied by a correction factor, the numerical value of which is 0.07÷0.09 units. Its meaning can be found in the cubature reference book.
Board cubic capacity calculator
If you need to do a calculation, the board cube calculator below will help you find the value you're looking for in seconds.
Timber and board - one of the oldest building materials, but it does not lose its relevance today. At the same time, the cost of these lumber forces buyers to be careful about the accuracy of calculating the required quantity.
Now you can find on the World Wide Web the necessary tables for calculating the required number of cubic meters of building materials, but a skillful owner must be able to carry out the calculation independently.
How many boards are there in a cube of 50 by 150 by 6000
As you probably already understood, the calculation of lumber is carried out in cubic meters. At the same time, a cube of boards and timber may have different overall dimensions. Therefore, for an accurate purchase, you need to understand the size of this cube for a more accurate calculation. The most common cube of lumber has dimensions of 50x150x6000 mm.
We calculate the required volume easily and simply
It is very easy to calculate cubic meters of boards or timber. To do this, you need to have basic knowledge of geometry, which we were taught at school. Thus, to determine the required cubic capacity, you need to initially multiply the width (l), thickness (s) and length (b).
Eg: s boards × l boards x b boards = 50 mm × 150 mm x 6000 mm = 45000 cm/cube.
We remember that a cubic meter is equal to 1,000,000 cubic centimeters, that is, 100 cm x 100 cm x 100 cm.
1000000 cc/cm: 45000 cc/cm = 22.22 pieces boards in one cube.
How many boards in 1 cube table 6m:
| Board size | Volume of 1st board | Boards in 1 cube in pieces | Square meters in 1 cube |
|---|---|---|---|
| Fifty | |||
| Board 50x 100x 6000 | 0.03 m³ | 33 pcs. | 20 m² |
| Board 50x 120x 6000 | 0.036 m³ | 27 pcs. | 20 m² |
| Board 50x 150x 6000 | 0.045 m³ | 22 pcs. | 20 m² |
| Board 50x 180x 6000 | 0.054 m³ | 18 pcs. | 20 m² |
| Board 50x 200x 6000 | 0.06 m³ | 16 pcs. | 20 m² |
| Board 50x 250x 6000 | 0.075 m³ | 13 pcs. | 20 m² |
As you can see, calculate required amount 6-meter boards are very easy. Now you know how to determine how many meter boards are in a cube. Depending on the size, you simply substitute required sizes V simple formula and get the finished result.
The generally accepted measure for measuring wood materials is the cubic meter. Most of all sawn products - edged, not edged, planed and others wood materials measured in cubic meters. In other words, 1 m 3 is a volume equal to 1 m in length, width and thickness.
How many cubes are in one board 40x150x6000
The calculation of the cubic capacity of wood depends on two of its characteristics, and in particular on whether it has been processed or not.
To find out how many cubes are in one 40x150x6000 board (edged), you should use a calculation table or the following formula:
V=a × b × l, where
- a – height;
- b – width;
- l – length.
The volume is calculated in cubic meters, so all values should first be converted from meters to millimeters. Accordingly, the thickness of this material is 0.04 m, width 0.15 m, and length 0.6 m. The next step is to directly calculate the cubic capacity:
- V=0.04 × 0.15 × 6 = 0.036
Accordingly, in one edged 6-meter "magpie" - 0.036 m 3.
There are no exact tabular data for unedged ones. Average cubic capacity wooden element with a cross section of 40 x 6000 - 0.05 m 3.
How many boards in a cube
Edged lumber 40 × 150 × 6000 is widely used in construction and furniture production, for the manufacture of containers, in interior design and other purposes. To find out how many “forty” pieces are in a cube, you need to find out the cubic capacity of the 1st board. Further calculation is not particularly difficult; you just need to use a special calculator or the following formula:
K=1 m 3 /Vd, where Vd is m 3 of the plank.
In our case, the calculation will look like this:
K=1/0.036 = 27.777 pcs.
Accordingly, in 1 cubic meter of lumber with a cross-section of 40 × 150 × 6000 there will be approximately 28 pieces. It's better to round up.
How many meters in a cube
In 1 cubic meter of lumber there can be different quantities square meters. This indicator depends on the thickness of the product. Therefore, to find out how many meters there are in one cube of wood, you need to divide 1 m3 by the thickness.
T=1/a, where:
- a – width.
In our example, the thickness of the lumber is 40 mm, which is correspondingly 0.04 m. We substitute it into the formula and get:
T=1/ 0.04 = 25 m2
As a result, 1 cubic meter of board 4 centimeters thick will be equal to 25 m2.
The cubic capacity of one edged board with a thickness of 40 mm
The cubic volume of edged lumber is 40 x 150 x 6000, as well as the number of boards and square meters per 1 cubic meter, can be seen in the table. It will help you correctly determine the required volume of building materials so as not to incur unnecessary costs when purchasing them.
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 appearance Aesthetics are not that important. 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, edged timber is purchased, but planed timber 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. Edged board 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 many square meters are in a cube? 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.
