Question: Determine the thickness ( in cm) of a rectangular piece of aluminum foil that is 17.0 inches long and 3.0 inches wide, with a mass of 2.21 grams. The density of aluminum is 2.70 ( g/ cm^3

I need to see the complete problem broken down to understand how to do this problem! I am stuck help! Thanks... Deb.

Determine the area of the foil, then from the mass determine the volume. Then you can determine the thickness.
