Thickness

Calculate density, and discover substances by using a density graph. Density is actually a measure of how much mass within a certain

volume. This physical property is normally used to determine and classify substances. As well as expressed in grams every cubic centimeters, or g/cm3. The chart on the proper lists the densities of some common materials.
