Question

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.

Answer 1

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.

Answer 2

Thank you so much I finally got it!!
