Question

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

• A. 343 $m^3$
• B. 1000 $m^3$
• C. 2000 $m^3$
• D. 3000 $m^3$

Answer 1

The correct option is B

1000 $m^3$

Let the side of a cube is $a$

Area of a face =$100m^2$

$\Rightarrow a^2=100$

$\Rightarrow a=10m$

$\Rightarrow$ Volume $=a^3=1000m^3$
