Question

Find the volume of a pyramid whose square base is 10 cm. and height 8 cm

Answer 1

Length of the side of the square base = 10 cm
Height of the pyramid = 8 cm
$\text{So, Area of the Square base}=10\text{cm}\times 10\text{cm}=100c{m}^2$
$\text{Volume of the pyramid}=\frac{1}{3}\times \text{Area of the base}\times \text{height}$
$=\frac{1}{3}\times 100c{m}^2\times 8cm$
$=\frac{800}{3}c{m}^3$
$=266\frac{2}{3}c{m}^3$
