A sheet of aluminum foil has a total area of 1.000 ft^2 and a mass of 3.366 gWhat is the thickness of the foil in millimeters (density of Al 2.699 g/cm^3)?answer: mm
Density Volume weight You are given both density and weight so the equation can be rearranged: weight/density volume 3.366g/2.699g/cm^3 X cm^3 X 1.247 cm^3 1.247 cm^3 is equal to 4.40419298 E-5 ft^3Volume area width or width volume/area width 4.404E-5 ft^3/1 ft ^3 4.404E-5 ft thick or 0.0134 millimeters
