Convert 75.0 ft^2 to cm^2. Convert 12 oz to grams. Use mass = volume x density to solve for volume, then
volume = area x thickness.
Solve for thickness and convert to mm.
A package of aluminum foil covers 75.0 ft^2 and weighs 12 oz. Aluminum has a density of 2.70 g/mL. What is the thickness of the foil in millimeters?
(1 in = 2.54 cm, 1 oz = 28.4 g, 1 mL = 1 cm^3)
