Question

Find the volume of a pyramid whose square base is 3 cm long and height 8 cm.

• A. $9c{m}^3$
• B. $24c{m}^3$
• C. $34c{m}^3$
• D. $12c{m}^3$

Answer 1

The correct option is B $24c{m}^3$

We know that,

volume of pyramid
$=\frac{1}{3}\times Areaofbase\times height$

Given,
height = 8 cm and the base is a square with side length 3 cm.

Volume of pyramid
$=\frac{1}{3}\times Areaofbase\times height$

$=\frac{1}{3}\times 3^2\times 8$

$=24c{m}^3$
