Question

the total surface area of a cube is 216 cm square . find the volume of the cube

Answer 1

area of cube = 6a square

= so, one side is 6cm

=> a = 6

volume of cube = a cube

= 6 cube

= 216cm cube

Answer 2

hi friend

total surface area of cube = 6a²

total surface area of the given cube = 216 cm²

∴ 6a² = 216 cm²

  a² = 216÷ 6

  a² = 36

   a = √36

  a = 6 cm

one side of the cube = 6 cm

volume of cube = a³

volume of the given cube = 6³

                                           = 216 cm³
