The formula
cube: a³ · box: l·w·h · sphere: 4⁄3πr³ · cylinder: πr²h · cone: ⅓πr²h
Volume counts unit cubes. The elegant relationships are worth remembering: a cone holds exactly one third of the cylinder that encloses it, and a sphere exactly two thirds — a result Archimedes was proud enough of to have carved on his tomb.
