Why would a cube measuring 20 cm3 and 2 kg float and a cube measuring 5 cm3 and 25 kg sink?
The cube with the larger volume and small mass is less compact than the cube with a small volume and large mass.
Calculate the mass of a liquid with a density of 5 g/mL and a volume of 20.5 mL.
m = dv = (5)(20.5) = 102.5 g
