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/cm3 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/cm3 x VOLUME
or the 14 grams of aluminum takes a volume of 5.0 cubic centimeters.
14/2.8 = 5.0 cm3
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 cm2 x Height cm = 5 cm3
Height= 5/306.5 = 0.0163 cm.
