Question

If LSA of cube is 256cm^2, what is it's volume.

Answer 1

lateral surface area of a cube= 4*side square
LSA= 256cm^2
4*s^2= 256
s^= 64
s= 8cm

volume= side^3
= 8^3
= 512cubic cm

Answer 2

L.S.A of cube = 256cm²

Or, 4a²= 256

Or,a²= 256/4

Or, a² = 64

or, √a² = √64

Or, a = 8 cm.

Side of cube = 8cm.

Volume = a³ = 8³cm³= 512 cm³.
