Find the lateral area of cube with side length 4 meter.

Solution

The lateral area of a cube = 4a² square units

Given, a = 4

So, the lateral area of the given cube = 4 * 4²

= 4* 4* 4

= 64

The lateral area of the given cube is 64 square meter.

Find the lateral area of cube whose side length is 3 feet.

Solution

The lateral area of a cube = 4a² square units

Given, a = 3

So, the lateral area of the given cube = 4 * 3²

= 4 * 3 * 3

= 36

The lateral area of the given cube is 36 square feet.
