Density can be determined by the
mass of an object and how much it takes up space (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. The answer would be A. 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
