A copper penny has a mass of 3.1 g and a volume of 0.35 cm^3. What is the density of copper?
8.9 g/cm^3
A student finds a shiny piece of metal that she thinks is aluminum. In the lab, she determines that the metal has a volume of 245 cm^3 and a mass of 61.2 g. Calculate the density.
2.50 g/cm^3
What is the mass of a cube of aluminum that is 3.0 cm on each edge? The density of aluminum is 2.7 g/cm^3.
73 g
You decide you want to carry a boulder home from the beach. It is 30 centimeters on each side, and so has a volume of 27,000 cm^3. It is made of granite, which has a typical density of 2.8 g/cm^3. How much will this boulder weigh?
75,600 g
Rocks are sometimes used along coasts to prevent erosion. If a rock needs to weigh 2,000 kilograms (about 2 tons) in order not to be shifted by waves, how big (what volume) does it need to be? You are using basalt, which has a typical density of 3200 kg/m3
0.625 m^3
