It is used in designing ships and submarines.
It is used in determining relative density of substances.
Hydrometers used to determine the density of liquids, work on this principle.
Lactometers used to determine purity of milk, are also based on this principle.
It is because of this principle that ship made of iron and steel floats in water whereas a small piece of iron like nail, sinks in it.
