Density can be determined by the
mass of an object and how much it takes up space (volume). Or density is equal to mass over volume. It is represented by
the formula D = M/V where D is the density in kg/m^3 or lb/ft^3, M is the mass
in kg or lb and V is the volume in m^3 or ft^3.
For example, you are given the mass of an
object of 40.5kg and a volume of 15m^3. Find its density.
D = M/V
D = (40.5 kg)
/ (15 m^3)
D = 27/10 or
2.7 kg/m^3
