Question

The total surface area of a cube is 216 cm square find its volume

Answer 1

Total surface area = 216 cm²

Let the side of the cube = a

Thus 6a² = 216

⇒ a² = 216/6

⇒ a² = 36

⇒ a = √36

⇒ a = 6 cm

Volume = a³ cm³ = 6³ cm³ = 216 cm³

please mark me as brainliest

Answer 2

6a^2=216
a=6

volume=6×6×6
216cm^3
