(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

You use exactly 3.0 gallons of paint to paint the walls of a room that measures 12 meters long by 12 meters wide by 8.0 meters high. How thick is the layer of paint that you put on the four walls? (No windows or doors) Use the conversion 1 gallon = 3.79 x 10^{-3}m^{3}.

2. Relevant equations

Possibly:

Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac

or

Volume of a Rectangular Prism = a b c

or Thickness= V/Area

3. The attempt at a solution

I converted the 3 gallons to m^{3}and got .01137 m^{3}. I just am not really sure what to do next. I've tried playing around with the different formulas above, but nothing seems to come out right. The answer is supposed to be 3.0 x 10^{-5}m. Seems like this question should be really easy...and it's making me feel really dumb for being unable to solve it. Any help would be much appreciated! Thanks!
