Question

the lateral surface area of the cube

Answer 1

Lateral surface Area of a cube with side " a " = 4a²

Now,

Let the side be a.

Given Lateral Surface Area = 256 cm²

So,

4a² = 256

a² =( 16/2)²

a = 16/2 = 8 .

Therefore , Side of the cube is 8cm

Answer 2

Lateral surface area of cube=4(side) ^2
Let side=a
256=4(a) ^2
256/4=a^2
64=a^2
(64)^2=a
(8×8)=a
8=a

Side of cube=8cm
