The density of an object or substance is its mass divided by its volume: Density = Mass ÷ Volume.
The units of density depend on the units used for mass and volume, but are usually: /³ (if mass is measured in g and volume in cm³).
The more dense a substance is, the heavier it feels for its size.
Density values
The densities of some everyday substances are:
Steel has a density of 7.82 /³
Water has a density of 1.00 /³
Air has a density of 0.0013 /³
These values show that the steel (solid) is the most dense while the air (gas) is the least dense.
