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 hexahedron. Each faces have 4 edges and totally there are 12 edges in a cube.

Surface Area of a Cube

The Surface Area of a Cube Formula is, 

\[\large Surface\;area\;of\;Cube=6a^{2}\]

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 x 52 cm2
= 6 x 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 x 172 cm2
= 6 x 289 cm2
= 1734 cm2
