If aluminum has a density of 2.7g/cm^3,what is the mass,in grams of the foil?
It states that a package of aluminum foil is 54.3 yd long, 14 inches wide, and 0.00035 inches thick.

You need to convert 54.3 yd to cm, 14 inches to cm and 0.00035 inches to cm. Then multiply length x width x thickness to obtain the volume in cubic centimeters. Then mass = volume x density and mass will be in grams.
