# How to find out sample of concrete cubes for different types of volumes In this construction video tutorial, one can learn how to find out the numbers of concrete cube samples for different volumes.

When casting is done at the construction site from a batching plant or other equipments, readymade concrete mix RMC) is produced. If you want to know how much samples are required for different types of concrete volumes for testing and checking compressive strength, the following formula should be applied.

A batching plant is an equipment that amalgamates different types of components to develop concrete. Some of these inputs range from water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement.

We, know 1 sample is similar to 3 specimens
Alternatively, 1 sample = 3 Nos. of cube

In the following table, the volumes of concrete are given in m3 as well as number of samples

If the concrete volume of the casting is between 1 to 5 cubic meter, total numbers of cubes will be 1 x 3 = 3 (here, number of samples = 1)

If the concrete volume of the casting is between 6 to 15 cubic meter, total numbers of cubes will be 2 x 3 = 6 (here, number of samples = 2)

If the concrete volume of the casting is between 16 to 30 cubic meter, total numbers of cubes will be 3 x 3 = 9 (here, number of samples = 3)

If the concrete volume of the casting is between 31 to 50 cubic meter, total numbers of cubes will be 4 x 3 = 12 (here, number of samples = 4)

If the concrete volume of the casting is between 51 to 100 cubic meter, total numbers of cubes will be 5 x 3 = 15 (here, number of samples = 5)

If the concrete volume of the casting is between 101 to 150 cubic meter, total numbers of cubes will be 6 x 3 = 18 (here, number of samples = 6)

If the concrete volume of the casting is between 151 to 200 cubic meter, total numbers of cubes will be 7 x 3 = 21 (here, number of samples = 7)

If the concrete volume of the casting is between 201 to 250 cubic meter, total numbers of cubes will be 8 x 3 = 24 (here, number of samples = 8)
