```							Use Archimedes' PrincipleEquate the mass of the cylinder to the mass of the water displaced by the cylinder.Mass = volume x density. For the cylinder, volume = (cross-sectional area) x length. For the water, volume = (cross-sectional area)x7. The cross-sectional area cancels out and we can easily calculate the density of the cylinder. The density is 0.7 g/cm3.
