Density (symbol: ρ - Greek: rho) is a measure of mass per unit of volume. The higher an object's density, the higher its mass per volume. The average density of an object equals its total mass divided by its total volume. A denser object (such as iron) will have less volume than an equal mass of some less dense substance (such as water).

Greek: The noun Greek refers to:...

Mass: Mass is a property of physical objects that, roughly speaking, measures the amount of matter they contain. It is a central concept of classical mechanics and related subjects....

Volume: Volume, also called capacity, is a quantification of how much space an object occupies. The SI unit for volume is the cubic metre. American spelling is cubic meter....
