Concrete Cube Formula

To calculate the compressive strength of the concrete cube, divide the maximum load applied on the cube during the test by the cross-section area of the cube and take the average of all the cubes results to get the exact compressive strength of the concrete.
The result should be expressed to the nearest 0.5 N/mm².
Note that Specimens that are clearly defective or have strengths that deviate by more than 10% from the average value of all test specimens are not considered.
