Answer:

1.4\ gallons

Step-by-step explanation:

Step 1

Find the area of one wall

Multiply the high by the wide

so

A=7*8=56\ ft^{2}

Step 2

Find the area of four walls

Multiply the area of one wall by four

A=4*56=224\ ft^{2}

Step 3

By proportion calculate how many gallons of paint are needed

\frac{1}{160} \frac{gallon}{ft^{2}}=\frac{x}{224} \frac{gallons}{ft^{2}}\\ \\x=224/160\\ \\x=1.4\ gallons
