How to Calculate and Solve for the Volume and Length of a Cube | The Calculator Encyclopedia

The image above is a cube.

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

The formula for calculating the volume of a cube is;

V = l3

Where;

V = Volume of a cube
l = Length of a cube

Let’s solve an example:
Find the volume of a cube where the length of a cube is 4 cm.

This implies that;
l = length of the cube = 4 cm.

V = l3
V = 43
V = 64 cm3

Therefore, the volume of the cube is 64 cm3

Calculating the Length of a cube using the Volume of the cube.

The formula is l = 3√V

Where;

V = Volume of a cube
l = length of a cube

Let’s solve an example:
Find the length of a cube where the volume of the cube is 120 cm3

This implies that;
V = Volume of the cube = 120 cm3

l = 3√V
l = 3√120
l = 4.93

Therefore, the length of the cube is 4.93 cm.
