Finding the density of solids requires a method of measuring the volume of the solid. If the solid has a regular geometric shape, the volume can be calculated from a measurement of the dimensions of the shape. Consider the Object A below. Given that its mass is 78.652 g and its dimensions are: width = 0.80 cm, height = 1.68 cm, length = 5.50 cm , what is the density of Object A? 11 g/cm3

9.9 g/cm3

7.4 g/cm3

8.0 g/cm3
