Density and Metric Review
Hopefully you have your calculator handy, as well as your formula sheet
1. Calculate the density of a film canister (cylinder) with a radius of 2.5 cm and a height of 4
cm. The canister is full of pennies and has a mass of 42 grams.
2. Will the canister in question one float, sink or flink? Explain why in one sentence.
3. A cube with sides of 2 meters has a mass of 14 grams. What is the density of the cube?
4. Alden has a crown with a mass of 85 grams and is supposed to be made of platinum. He
knows platinum has a density of 20.1 g/cm3. What volume should the crown have?
5. Claire’s textbook measures 3.0 cm by 6.0 cm by 4.0 cm and has a mass of 80.0
grams. What is the density of the book? Would the book float in water?
6. Joseph has cup of reddish colored marbles. When measured it had a mass of 425 grams. By
water displacement, the volume of the marbles was calculated to be 48.0 cm3. Given the
following densities, identify the metal.
Gold: 19.3 g/mL
Copper: 8.86 g/mL
Bronze: 9.87 g/mL
7. Gabi has a big gulp from Holiday. The volume of the cylinder container has a height of 35
cm, and radius of 15 cm. What is the volume of liquid it can hold?
8. Pure water has a density of 1.0 g/cm3. Group the following based on whether they will float,
sink, or “flink” when placed in water.
