Solution

The volume of a cube = (side)³

(1) The side of cube = 2 m
Using the above formula for finding the volume of a cube:
Volume = (side)³ = (2)³ m³
= 8 m³

(2) The side of cube = 5 m
Using the above formula for finding the volume of a cube:
Volume = (side)³ = (5)³ m³
= 125 m³

(3) The side of cube = 8 cm
Using the above formula for finding the volume of a cube:
Volume = (side)³ = (8)³ cm³
= 512 cm³

(4) The side of cube = 4 cm
Using the above formula for finding the volume of a cube:
Volume = (side)³ = (4)³ cm³
= 64 cm³

(5) The side of cube = 10 cm
Using the above formula for finding the volume of a cube:
Volume = (side)³ = (10)³ cm³
= 1000 cm³
