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?

1.4

7 x 8 = 56 sq ft per wall

56 x 4 = 224 sq ft for all 4 walls

224 divided by 160 = ??

What type of paint for shed

To determine the number of gallons of paint needed, we need to calculate the total surface area of the shed's walls and then divide it by the coverage of one gallon of paint.

First, let's calculate the area of one wall:
Area of one wall = height × width
Area of one wall = 7 ft × 8 ft = 56 sq. ft

Since the shed has four walls, we need to multiply the area of one wall by 4 to find the total surface area of the shed:
Total surface area of the shed = 4 × 56 sq. ft = 224 sq. ft

Now, we'll divide the total surface area of the shed by the coverage of one gallon of paint to find the number of gallons needed:
Number of gallons = Total surface area ÷ Coverage of one gallon
Number of gallons = 224 sq. ft ÷ 160 sq. ft/gallon

When we divide 224 sq. ft by 160 sq. ft/gallon, we get:
Number of gallons ≈ 1.4

Therefore, you will need approximately 1.4 gallons of paint to paint the storage shed. Since you cannot purchase a fraction of a gallon, you would need to round up to the nearest whole number. So, you would need 2 gallons of paint.
