Calculating Concrete Requirements: How many cubic meters do i need?The first step in determining the concrete mixing requirements is, of course, the calculation of the volume to be filled. Classically, a cuboid with height, width and length is calculated here. If you want to make concrete furniture yourself, you may also have other shapes in mind, such as cylinders, cones or the like. There are also the right formulas for this. For example, for calculating a circle section to determine the base areas of individual parts. But let’s stick to the cuboid as the simplest body to be calculated. For the rectangular area you want to fill with concrete, first measure the height, width and length in meters. For example, let’s assume a room with a width of 2m and a length of 3.6m. The concrete is to be poured 10cm, i.e. 0.1m high. This results in the following calculation:
2m x 3,6m x 0,1m = 0,72m³This means that you need 0.72 cubic metres of concrete for the floor of the room. If you need help calculating or want to check your results, you can use the calculator on your PC, Mac, smartphone or tablet. Or you can visit an online calculator for cubic meters, like this one (click here).
Calculate Cylinder VolumeAs can be seen above in the picture, concrete cylinders are well suited as decoration and demarcation in the garden. With a cylinder as a geometric shape, the volume calculation is a bit more complicated, but not impossible either. What you need is on the one hand the height of the concrete cylinder and on the other hand its base area. The height can easily be determined with a ruler or folding ruler. Calculate the base area as follows:
A=π*r² (A = area; r = radius) / or alternatively: A=(π*d²)/4 (d = diameter)Use a value for r or d in meters for the calculation. Also use a meter for the height of the cylinder. Then simply calculate V=A*h (V = volume; h = height) for the volume. A more detailed explanation and calculation examples for cuboids, cylinders and spheres can be found here (click).
