Roberto has two cubes made of different substances. The dimensions of the cubes are shown in the illustration below. Roberto measures the mass of each cube using a
balance and records the measurements in the table below. When Roberto places the
cubes in water, he finds that one cube floats, and one cube sinks. (Remember density
of water is 1.0 g/mL)
What is the density in grams of the cube that will sink in water? Round to the nearest
tenth.
