The aluminum in a package containing 75 ft^2 of kitchen foil weighs approximately 23 ozAluminum has a density of 2.70 g/cm^3What is the approximate thickness of the aluminum foil in millimeters? (1 oz28.4 g)Please help? I can't get from volume to thickness in mmI have the answer, I just don't know how to get it.
First, 23oz 28.4g/oz 652.039g and 75ft^2 69677.28 cm^2 (all this is, is converting US units to SI units, so you're working with the units that are asked for in the problem) 652.039g / 2.70g/cm^3 241.49 cm^3 (mass / density volume) 241.49 cm^3 / 69677.28 cm^2 .003 cm (volume / area length (or thickness in this case)) .003 cm .03mm (1 cm 10mm)
