Suppose the perimeter of one face of a cube is 24 cm. What is its volume?

Given, the perimeter of one face of a cube is 24 cm.


We know, Perimeter of one face of a cube = 4 × side


∴ Perimeter of one face of a cube = 4 × side


24 = 4 × side



Side= 6 cm


We know, Volume of a cube = (side)3


∴ Volume= (6)3


= 6×6×6


= 216 cm2
