Answer:
0.2129 mm
Explanation:
We have given volume of the paint = 1 gallon[tex]=3.79\times 10^{-3}m^3[/tex]
Area that covers the paint [tex]=17.8 m^2[/tex]
We have to find the thickness of the fresh paint
So [tex]thickness=\frac{volume}{area}=\frac{3.79\times 10^{-3}}{17.8}=0.2129\times 10^{-3}m=0.2129mm[/tex]
So the thickness of fresh paint on the wall is 0.2129 mm
