Question

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

Answer 1

The volume of the pyramid whose square base is 10 cm and height is 8 cm, is 266.67 $cm^{3}$.

Tips:

If $a$ be the length of the sides of the square base and $h$ be the height of the pyramid, then its volume is given by

$\quad V=\dfrac{1}{3}a^{2}h$

Step-by-step explanation:

Given, the sides of the square base is 10 cm.

Then its area is $a^{2}=10^{2}\:cm^{2}=100\:cm^{2}$

Also, its height is $h=8\:cm$.

Therefore, the volume of the pyramid is

$\quad V=\dfrac{1}{3}a^{2}h$

$\Rightarrow V=\dfrac{1}{3}\times 100\times 8\:cm^{3}$

$\Rightarrow V=\dfrac{800}{3}\:cm^{3}$

$\Rightarrow \bold{V=266.67\:cm^{3}}$
