volumes of the prism and the pyramid.
 

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 3∶ 1

Given that

A prism and a pyramid have the same base and the same height.

As we know that

The volume of a prism = The area of the base of the prism × height of the prism

and

The volume of a pyramid = 1/3 ×  The area of the base of the pyramid × height of the pyramid

Hence, the required ratio = 1/(1/3) = 3/1

= 3: 1
