Q2 of 20 Page 219

The total surface area of a cube is 1350 sq.m. Find its volume.

Given, total surface area of a cube = 1350m2

Let side of the cube be ‘a’


Formula used:- volume of cube = a3


Total surface area = 6a2


Hence, 6a2 = 1350


a2 =


a =


a = 15m


volume of the cube = a3


= 153


= 3375m3
