FOR M10 = COMPRESSIVE STRENGTH = 10 N/SQ MM
FOR M15 = COMPRESSIVE STRENGTH = 15 N/SQ MM
FOR M20 = COMPRESSIVE STRENGTH = 20 N/SQ MM

Answer / ali

Why the compressing strength of the cubic sample (15X15X15) is
more than the sample (20X20X20)?
Due to the compressing stress relation (Load/Area), the
strength should be increased by increasing the area of the
sample.
