Question

A square pyramid has a volume of 3600 ft3. If all lengths of the pyramid are multiplied by 0.25, what will the resulting volume be? A. 52.5 ft3 B. 72.75 ft3 C. 64 ft3 D. 56.25 ft3

Answer 1

You are given the volume of a square pyramid of 3600 ft³. And if all lengths of the pyramid are multiplied by 0.25 then the volume is

V = 1/3BH (let us assume that they have equal sides)
3600 ft³ = 1/3x³
x = 22.104 ft

V = 1/3(22.104)³(0.25)³
V = 56.25 ft³
The answer is letter D.
