If the object is a regular shape, the volume can be found by measuring length, breadth and height and using the equation:
Volume = length x breadth x height
If the object has an irregular shape, the volume can be measured using a measuring cylinder or a displacement can.
Volume of stone = Final Volume – Initial Volume
Volume of stone = 75 cm3 – 50 cm3 = 25 cm3
If the mass of the stone is measured using a top pan balance and found to be 175 g.
Density of the stone is 7 g/cm3
The volume of larger irregular objects can be measured using a displacement can.
