g a package of aluminum foil contains 50 ft2 of foil, which weighs approximately 8.0 oz. aluminum has a density of 2.70 g/cm3. what is the approximate thickness of the foil in millimeters

1.8*10^-2mm or 0.018mm

Explanation:

Density = mass/Volume

But volume = area*thickness

Area = 50ft2 = 46451.52cm2

Mass=8oz = 226.7962g

Density = 2.70g/cm3

Thickness = mass/density * area

= 226.7962/46451.52*2.70 = 1.8*10-3cm = 1.8*10^-2mm
