Verifying Volumes of a Regular Object

When the volume of a cube or cuboid is measured, it can be verified using other means called the displacement method. In this method. A quantity of water is poured into a measuring cylinder and the volume is recorded (example. 30cm³). The object is carefully immersed in the water and the final volume is recorded (60cm³).

The initial volume is subtracted from the final volume and the volume of the object is verified.

i.e. A cuboid of length 5cm³, breadth 3cm³ and height 2cm³.

Volume = length x breadth x height

= 5cm³ x 3cm³ x 2cm³

= 30cm³

Verification of the volume of the cuboid

Initial volume of water = 30cm³

Final volume of water = 60cm³

Volume of cuboid = Final volume of water – Initial volume of water

= 60cm³ – 30cm³

=30cm³
