Question

The total surface area of a cube is 1350 sq. m. Find its volume.

Answer 1

Given total surface area of cube $=1350sqm$

Let the side of the cube is $s$ meter

Then the surface area of cube $=6s^2=1350$

$\Rightarrow s^2=225$

$\Rightarrow s=15$ m

Then side is $15$ m

Then volume of cube =$s^3=(15{)}^3=3375m^3$
