The total surface area of a solid cube is 2400 cm2. The volume of the cube is:
Answer & explanation
Correct answer: option 4
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
