Question

A block of stone is cut so that its cross-section is a parallelogram. The width of the bottom side is

a. greater than the width of the top side.
b. less than the width of the top side.
c. equal to the width of the top side.
d. independent of the width of the top side.

Answer 1

The width of the bottom side of the stone block is greater than the width of the top side.

Step-by-step explanation:

The width of the bottom side of the stone block is greater than the width of the top side.

This can be understood by considering the cross-sectional areas of the two blocks, A and B. The cross-sectional area of Block A is L x 2L = 21², while that of Block B is 2L x 2L = 41². Because the cross-sectional area of Block B is twice that of Block A, it means that the width of the bottom side of Block B is greater than the width of the top side.
