Answer:
[tex]1.4\ gallons[/tex]
Step-by-step explanation:
Step 1
Find the area of one wall
Multiply the high by the wide
so
[tex]A=7*8=56\ ft^{2}[/tex]
Step 2
Find the area of four walls
Multiply the area of one wall by four
[tex]A=4*56=224\ ft^{2}[/tex]
Step 3
By proportion calculate how many gallons of paint are needed
[tex]\frac{1}{160} \frac{gallon}{ft^{2}}=\frac{x}{224} \frac{gallons}{ft^{2}}\\ \\x=224/160\\ \\x=1.4\ gallons[/tex]
