Question

The area of the base of a prism is $90c{m}^2$. Find the height of the prism if its volume is $7200c{m}^3$.

Answer 1

Area of the base of the prism $=90{\text{cm}}^2$
Volume of the prism $=7200{\text{cm}}^3$

Let '$h$' be the height of the prism.

$Volume=Areaofthebase\times Height$

$\Rightarrow 7200=90\times h\Rightarrow h=\frac{7200}{90}=80$
$\therefore$ The height of the prism is 80 cm.
