Question

The volume of a cube is 21952 cube surface area is

Answer 1

Given:

Volume of cube = a^3 = 21952

To find :

Surface area = ?

Total surface area = 6a^2

Lateral surface area = 4a^2

from the given data ,

a^3 = 21952

» a = 28 [Taking cube root on both sides]

substituting the values , we get,

Total surface area = 6a^2

» 6(28)^2

Or, 6x784

Or, 4704 units^2

Lateral surface area = 4a^2

» 4(28)^2

Or, 4x784

Or, 3136 units^2
