An electrolytic tin-coating process gives the coating 30 millionths of an inch thick. How many square meters can be coated with one kilogram, density 7.30 g/cm^3?

30 millionths inch = 30/1,000,000 inch = 30E-6 inch thick.

30E-6 inch x (2.54 cm/in) = 7.62E-5 cm = 7.62E-7 meters.

Mass = volume x density

1,000g = volume x 7.30

volume = 1000/7.30 = about 137 cc = 137E-6 cubic meters.= 1.37E-4 cubic meters.

volume = length x width x height

1.37E-4/7.62E-7 = length x width = ?

sqrt ? = length of each leg of the square. Check my work.
