Given, lateral surface area of a cube = 100 m²
We know that, lateral surface area of a cube = 4 x (Side)²
⇒ 100 = 4 x (Side)²
⇒ (Side)² = 100/4 = 25
⇒ Side = √25 = 5 m
[taking positive square root because side is always a positive quantity]
Now, volume of a cube = (Side)³ = (5)³= 5 x 5 x 5 = 125 m³
Hence, the volume of the cube is 125 m³.
