The total surface area of a solid cube is 2400 cm2. The volume of the cube is:

6000 cm3 8200 cm3 8400 cm3 8000 cm3

8000 cm3

The total surface area of a cube = 6a2 The volume of a cube = (side)3 6a2 = 2400 (Given) a2 = 400 a = \(\sqrt {400}\) = 20 Then the volume of a cube = (side)3 = (20)3 = 8000 cm3
