**Coke Can Problem Two: Thickness of the metal in the can**

**Question:**Coke cans are made of aluminum. The density of aluminum is 2.8 g/cm

^{3}How thick is the metal that makes up the Coke can if the empty Coke can weighs 14 grams or half an ounce?

We know that density x volume =mass so mass/density =volume

14 grams =2.8 g/cm

^{3 }x VOLUME
or the 14 grams of aluminum takes a volume of 5.0 cubic centimeters.

14/2.8 = 5.0 cm

^{3}
The volume of the aluminum is the surface area x height.

From problem one we know the surface area of the aluminum in the coke can is 306.6 square centimeters.

306.5 cm

^{2}x Height cm = 5 cm^{3}
or

Height= 5/306.5 = 0.0163 cm.

Again, please confirm. Also, please go back to the Coke Can Math Problem list and submit more questions or answers.
