Question

If the mass of a boy in 40 kg and its relative density is 1.1, find its volume in litres.

Answer 1

Volume = 36.36 litres

Explanation:

Relative density =  density of the boy / density of water  

Density of water is 1.

So Density of the boy = 1.1

Mass / volume = density = 1.1

40/ volume = 1.1

Volume = 40 / 1.1 = 36.36 litres
