An electrolytic tincoating 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 = 30E6 inch thick.
30E6 inch x (2.54 cm/in) = 7.62E5 cm = 7.62E7 meters.
Mass = volume x density
1,000g = volume x 7.30
volume = 1000/7.30 = about 137 cc = 137E6 cubic meters.= 1.37E4 cubic meters.
volume = length x width x height
1.37E4/7.62E7 = length x width = ?
sqrt ? = length of each leg of the square. Check my work.
