Question

A partly-full paint can has 0.52 gallons of paint left in it. (a) What is the volume of the paint, in cubic meters? (b) If all the remaining paint is used to coat a wall evenly (wall area = 15 m2), how thick is the layer of wet paint? Give your answer in meters.

Answer 1

a) .002 cubic meters . How do I find part b?

Answer 2

1 gallon = 4.5l = 4500cm^3. this means that 0.52 gallons = .52 * 4500 = 2340cm^3. this is the same as 0.00234m^3. for part b, 15m^2 * t = 0.00234m^3 where t is the thickness. you just have to solve for t, which gives you 0.000156m, or 0.156mm

Answer 3

Oh, thanks.
