Density is a measurement that compares the amount of matter an object has to its volume. An object with much matter in a certain volume has high density. An object with little matter in the same amount of volume has a low density.Density is found by dividing the mass of an object by its volume:

\displaystyle{ \rho = \frac{m}{V} }

where ρ is the density, m is the mass, and V is the volume.
