The image above is a cube.

To compute the perimeter of a cube, one essential parameter is needed and this parameter is length of one of the sides (a).

The formula for calculating the perimeter of a cube:

P = 12a

Where;

P = Perimeter of the cube

a = Length of one of the sides of the cube

Let’s solve an example;

Find the perimeter of a cube when the length of one of the sides is 14 cm.

This implies that;

a = Length of one of the sides = 14 cm

P = 12a

P = 12 x 14

P = 168

Therefore, the** perimeter of the cube** is **168 cm.**

**Calculating the Length of one of the sides of a Cube using the Perimeter of the Cube.**

a = ^{P} / _{12}

Where;

a = Length of one of the sides of the cube

P = Perimeter of the cube

Let’s solve an example;

Find the length of one of the sides of a cube when the perimeter of the cube is 200 cm.

This implies that;

P = Perimeter of the cube = 200 cm

a = ^{P} / _{12}

a = ^{200} / _{12}

a = 16.67

Therefore, the** length of one of the sides** is **16.67 cm.**
