Question

Ice (at 0 degrees celsius) has a density of 922 kg per meter cubed. If the edge of a cube of ice is 4 cm, what is the mass of the cube?

Answer 1

The volume of the cube is (0.04 m)^3 = 64*10^-6 cubic meters

Multiply that by the density to get the mass. If you use 922 kg/m^3, you get 0.059 kg or 59 g.

If it was liquid water it would have a mass of 64 g.
