Question

The area of one face of a cube is $100m^2$. Find the volume of the cube.

• A. 3000 $m^3$
• B. 2000 $m^3$
• C. 1000 $m^3$
• D. 500 $m^3$

Answer 1

The correct option is C

1000 $m^3$

Given,
Area of one face of cube = $100m^2$
Let side length of the cube be 'a' .
Area of cube is given by side${}^2$.
$\Rightarrow a^2=100$
$\Rightarrow a=10m$

Volume of a cube = side${}^3$
$\Rightarrow Volume=a^3={10}^3=1000m^3$
