What is the volume of a cube if the perimeter of one face of the cube is 40 cm?

Correct option is A

Given:
Perimeter of one face of the cube = 40 cm
Formula Used:
Side of cube = a units
Perimeter of cube = 4a units
Volume of cube = a³ cubic units
Solution:
Let the side of a cube = a cm
Perimeter of one face of the cube = 40 cm
4a = 40
a = 10 cm
Volume of the cube = a³ = 10³ = 1000 cm³
