The mass of a block made of certain material is `13.5 kg` and its volume is `15 xx 10^-3 m^3`. Will the block sink or float in water ? Give a reason for your answer.

Explanation

Density of block `= (13.5 kg)/(15 xx 10^-3 m^3) = 900 kg//m^3`
The block floats on water as its density is less than that of water, i.e., `1000 kg//m^3`.
