Surface Area of a Cube Formula

Surface Area of a cube is the total area of the outside surfaces of the cube. It is measured in terms of square unit. A cube has 6 identical square faces and hence it is also called as a hexahedron. Each face of a cube has 4 edges and totally there are 12 edges.

Surface Area of a Cube Formula

The Surface Area of a Cube Formula is,

Surface area of Cube = 6a2

Where “a” is the side length of the cube.

Solved Examples

Question 1: What is the surface area of a cube of side 5 cm?

Solution:

Given,
Side of the cube = a = 5 cm
Surface Area of a Cube = 6a2
= 6 × 52 cm2
= 6 × 25 cm2
= 150 cm2
Question 2: What is the surface area of a cube of side 17 cm?

Solution:

Given,
Side of the cube = a = 17 cm
Surface Area of a Cube = 6a2
= 6 × 172 cm2
= 6 × 289 cm2
= 1734 cm2
