Volume of a cube


Given the length of one side, call it a, the volume of a cube can be found by using the following formula:




Vcube = a3 = a × a × a

Cube with edge = a


Example #1:

Find the volume if the length of one side is 2 cm

Vcube = 23

Vcube = 2 × 2 × 2

Vcube = 8 cm3


Example #2:

Find the volume if the length of one side is 3 cm

Vcube = 33

Vcube = 3 × 3 × 3

Vcube = 27 cm3


Example #3:

Find the volume if the length of one side is 3/2 cm

Vcube = (3/2)3

Vcube = 3/2 × 3/2 × 3/2

Vcube = (3 × 3 × 3)/(2 × 2 × 2) Vcube = 27/8 Vcube = 3.375 cm3
