A mass of a body is 70 kg. When completely immersed in water it displaces 2000 cm3 of water. What is the relative density of the material of the body?

Solution

volume= 2000 cm3
or 2000 x 10⁻⁶ m₃ or 2 x 10⁻³ m₃

density= 70 kg / 2 x 10 ⁻³
= 5 x 10 ³

relative denisty= denisty of substance/ water density
= 35 x 10³ / 10³
=35
