Suppose you have two 100-mL graduated cylinders. In each cylinder there is 44.0 mL of water. You also have two cubes: one is lead (density = 11.3 g/mL), and the other
is aluminum (density = 2.70 g/mL). Each cube measures 1.9 cm on each side.
Part A
After you carefully lower each cube into the water of its own cylinder, what will the new water level be in each of the cylinders?
