You wish to paint a storage shed. Its four walls measure 7 ft. high and 8 ft. wide each. If one gallon of paint covers 160 sq. ft., how many gallons of paint will you need?

Paint required = gallons.

Respuesta :

1.4 gallons exactly or 2 gallon buckets

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]
