C. relative weight of a block of stone to its size.
D. force a block exerts on the blocks around it.
Answer:
A. ability to support pressure without breaking.
Step-by-step explanation:
Stone has been used as a building material since ancient times because of its compressive strength, which is the ability to support pressure without breaking.
Compressive strength can be defined as the ability of a structural element or particular material to withstand an applied, which is aimed at reducing the size of the structural element.
Simply stated, it is the ability of a structural element or material to withstand an applied load without deflections, fracture or having any crack.
In this context, a stone possesses the ability to resist or withstand compression loads.
Some examples of other materials or structural elements having good compressive strength are steel, bones, concrete etc. The standard unit of measurement of the compressive strength of a material is Mega Pascal (MPa) or pound-force per square inch (psi) in the United States of America.
