Density is defined as the mass per unit volume. In other words, density is how
heavy something according to it's size.If something is very heavy and small in
size, density is high. Density formula is : Density = Mass / Volume.
Unit of density in metric system is kilogram per cubic meters. So, if a cubic
meter of water weighs 1000 kilograms, it means water density is 1000 kilograms
per cubic metre. The density of air (at sea level) is 1.225 Kg/m3.
