The perimeter of one face of a cube is 40 cm. Its volume will be:
- A10 cm³
- B100 cm³
- C1000 cm³
- D10000 cm³
Solution & Step-by-step Explanation
Each face of a cube is a square.
Let the side length of the cube be a.
The perimeter of a square face is given by:
Perimeter=4a=40cm
a=
4
40
=10cm
The volume (V) of a cube is given by the formula:
V=a
