How to calculate how many boards are in a cube: table of timber volumes
When starting construction, any home craftsman is once faced with the need to purchase boards. And this is where the fun begins. Having calculated the necessary square by the width and length, the beginner grabs his head - what to do? After all, such material in construction markets is 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 unnecessary problems.
It is important to know not only the size of the lumber, but also its volume
No one will count the number of units of lumber - you can buy them only by cubic capacity

What types and types of material can be and their areas of application
Everyone understands that how many cubic meters will be needed for a particular construction will depend on the shape and size of the lumber. But first you need to understand what types and types of material can be found. The main ones are:
- Edged timber;
- Sliced timber;
- Sliced bar;
- Edged bar;
- Edged and floor boards;
- Unedged materials.
Each of these types has its own characteristics and is used in its own field. For example, a frame terraces in the country you can't build without timber, but sheathe a wall with them is the height of irrationality. For this, now we will consider each of these types separately.
By measuring the size of the board, you can calculate its quantity in a certain volume
Edged timber and its scope
Edged timber is used in cases where aesthetics are not so important in appearance. It can have cracks that occur during drying after processing.It is made by sawing out the central part from a regular log, and only after that it undergoes minimal drying. Although such lumber is considered expensive, it is still cheaper than planed products.
Sliced timber: what are its differences from edged
The differences are fundamental. If no preparation of the log is required for the manufacture of the previous version, then for the planed one it is pre-dried, and only after that it goes to the sawmill. The surface of such a product is smooth and polished. A beam of this type can even become a good decor element. Simply put, if it is necessary to erect walls for finishing, an edged beam is purchased, but a planed one does not require finishing. It can be simply varnished. If we talk about strength, then it is less for a planed product.
Bars and bars can be quite varied
Sliced bar - what are its differences from a bar
In essence, they are one and the same, the difference is only in size. The bar has a lower rib height, which means that it is not suitable for the construction of frames of buildings or residential buildings. Most often, this material is used for decorative purposes. It also finds application in the installation of frames for interior decoration or reinforcing jumpers of various wooden boards. The difference between edged and planed timber and the same types of timber is the same.
Edged and floorboard: their features and differences
The differences between these lumber are also noticeable at first glance. The edged board is not cut. It has an even shape, but, at the same time, it is in no way suitable for fine finishing. In contrast, the genital has three smoothly processed edges (except for the lower wide one) and often has a groove on one side on the narrow sides and a spike on the other. This is done to make them more tightly connected to each other, as well as to reduce loads and eliminate deformation of the floor during operation.
These lumber are called edged ...
... and this is already floorboards
Unedged materials - what they are
These are the cheapest products. When cutting a log, only two opposite sides are cut. Thus, the edges of the boards are uneven. Most 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 cannot be answered! Indeed, in order to determine this, you must at least know the thickness of the board. Without this parameter, no calculations will work. Let's try to figure out how to calculate the cubic capacity.
When finished perfectly, painting is not required. A simple varnish is enough
It does not present any big difficulties, but it requires care. We need to understand how many boards are in the cube. And for this you need to calculate the cubic capacity of one of them by size. For example, a board with a 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 m3... This will be the answer to the question of how to calculate the cubic capacity of the board.
If the material was lying close, then the volume could be measured with a tape measure. But then the wood spoils quickly
How many boards in a cube: table of average values
For example, there are boards with certain dimensions. 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 | Overpayment amount 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 |
Having figured out how to count cubic meters, you need to understand how to find out how much a cube of a board weighs.
If the wood is well dried, it can be packed in polyethylene
Average values of weight at different humidity
| Breed name | Raw, kg / m3 | Dry, kg / m3 |
|---|---|---|
| Birch tree | 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 borne in mind when planning transportation.
How to correctly calculate the amount of material
Let's consider how to correctly calculate how many pieces of boards will be in one cubic meter. This is done using the following formula:
1m3 / (L × h × b) = N pieceswhere
- L - board length;
- h - width;
- b - thickness.
As you can see, the calculations are not at all complicated.
It looks like unedged lumber
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. Often this size name can be heard in the construction markets.
Board cubic meter calculator or how to make calculations easier
The very algorithm of actions how to calculate a cubic meter by quantity is probably now clear. But there is not always a desire to engage in various calculations. And it's quite easy to make a mistake. Now we will show you how to calculate a cube board without making complex calculations.
Scheme of breaking up a log on a sawmill - different types of lumber will be obtained from it
For such cases, there are special programs called cubic meter calculators. How are they convenient? The main convenience of such programs is their accuracy. The calculator for calculating a board in a cube is devoid of the human factor, which excludes the possibility of errors in the calculation process. Another rather weighty argument in its favor is the speed of computing. You just need to enter the correct data in the appropriate fields and click on the "calculate" button. Nothing else is required from the user. The online calculator of planks in a cube will instantly give a result for the number.
Summarize
It is clear that accurate calculations of the volume of wood are necessary during construction work. But it is better to perform them using a special program that will eliminate the possibility of errors.
