2. A student needs to determine the density of two metal objects. The first object is a cube and the second object is a rectangular bar. The student uses calipers to measure the length of the objects. a. What is the density (in grams per milliliter) of the metal cube if it has a mass of 80.55 g and an edge length of 2.16 cm? mL b. What is the density (in grams per milliliter) of the rectangular bar if it has a mass of 186.77 g and measures 4.26 cm in length, 1.42 cm in width, and 19.21 cm in height? mL
