In order to determine these densities, we might weigh a cubic centimeter of each type of glass. If the flint sample weighed 7.2 g and the bottle glass 2.4 g, we could describe the density of flint as 7.2 g cm –3 and that of bottle glass as 2.4 g cm –3. (Note that the negative exponent in the units cubic centimeters indicates a reciprocal.A piece of flint 9-10 cm (3.5-3.9 in) long, weighing 171 grams.
