Question

What is the volume in cubic cm of a pyramid whose area of the base is $25sqcm$ height $9cm$?

• A. $70$
• B. $90$
• C. $60$
• D. $75$

Answer 1

The correct option is D $75$

Given

Area of base $25c{m}^2$

Height of pyramid $9cm$

Volume of pyramid is $\frac{1}{3}\times Area\times Height$

$⟹\frac{1}{3}\times 25\times 9$

$⟹25\times 3=75c{m}^3$
