Dec 15, 2008 · I did a cube crushing test in an experiment and for my two cubes i got the results of 29.84 KN and 24.19 KN now i need to work out the compressive strength compressive strength (N/mm^2) = maximum load / cross sectional area the dimensions of the cube was 100m x 100m x 100m I have to compare these with some set results that came out will compressive strengths of 50 - 37 .
