Water displacement is one technique to measure the density of solids. The volume of regularly shaped objects can be determined using a ruler. For example, for a rectangular solid, the formula for the volume is length x width x height. 1.A rectangular solid has a mass of 152.213 g and measures 7.50 cm by 3.00 cm by 1.50 cm. Calculate the density of the solid in units of g/cm3. Show work and report density with the appropriate number of significant figures.
