Calculate the volume of a steel bar with the following dimensions: Length = 5 cm Width = 2 cm Height = 30 cm

Calculate the volume of a paperback book with the following dimensions: Length = 12 cm Width = 3 cm Height = 20 cm

Now determine the density of the steel bar if its mass is 2.34 kg. (Hint: Convert to grams first.)

Water has a density of 1 g/cm3. If you placed a cork and a steel paper clip in a jar of water, what do you think would happen? Use your knowledge of density to explain the outcome.

A cork has a volume of 5.0 cm3 and a mass of 1.2 grams. Calculate its density
