Question

Derive the formula for the lateral surface area of a cube with the help of the formula for the area of the square and rectangle

Answer 1

Step-by-step explanation:

Lateral Surface area of a cube includes all the faces of a cube except the top and bottom faces

Let each side of a square be 'a'

We know that

Area of each face = side*side

= a²

Number of faces in LATERAL SURFACE AREA = 6

Therefore L.S.A = 6*a² = 6a²
