Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a physical
property of a substance that represents the mass of that substance per unit
volume. To determine the mass, we calculate the volume of the paper and multiply to the density. We do as follows:
Volume = 76 mm x 215.9 mm x 279.4 mm = 4584506.96 mm^3 or 4584.51 cm^3
Mass = 1.20 g/cm^3 ( 4584.51 cm^3 ) = 5501.41 g
