I think that this is right, but I assumed that the ceiling has the same dimensions as the wall you would need 4 gallons for 2 coats.
Work:
20x8= 160 (square feet for 1 wall)
160x5=800 (i assumed there are 4 walls and 1 ceiling)
800x2=1600 (you need 2 coats)
1600/400=4 (each gallon includes 400 square feet)

\end{array}\implies \cfrac{2\frac{1}{6}}{x}=\cfrac{\frac{2}{5}}{1}\implies \cfrac{\frac{2\cdot 6+1}{6}}{\frac{x}{1}}=\cfrac{\frac{2}{5}}{\frac{1}{1}}

\bf \cfrac{\frac{13}{6}}{\frac{x}{1}}=\cfrac{2}{5}\cdot \cfrac{1}{1}\implies \cfrac{13}{6}\cdot \cfrac{1}{x}=\cfrac{2}{5}\implies \cfrac{13}{6x}=\cfrac{2}{5}\implies 13\cdot 5=2\cdot 6x
\\\\\\
65=12x\implies \cfrac{65}{12}=x\implies \boxed{5\frac{5}{12}=x}
\\\\\\
\cfrac{5\cdot 12+5}{12}\implies \cfrac{65}{12}
