Question

Lateral surface area of cube is 324 metre square find the volume and total surface

Answer 1

volume 729 whle total surface area 486

Answer 2

lateral surface area of a cube=4a  square.
so 4a square =324 metre (given)
or,a square = 81 metre
or, a = √81 = 9 metres.
now volume of a square = a cube=a X a X a
                                       = 9 X 9 X 9
                                         =729
total surface area=6a square.
                            =6 X a X a
                             =6 X 9 X 9
                              =486 metre square
