Jake needs 2 gallons of paint to cover four walls measuring 10ft x 12ft each.
To calculate the total square footage that Jake needs to paint, we first find the area of one wall: 10ft x 12ft = 120 square feet. Since there are four walls, the total area to paint is 4 x 120 = 480 square feet. To determine the gallons needed, we divide the total area by the coverage of one gallon: 480 / 300 = 1.6 gallons. Therefore, Jake should purchase 2 gallons of paint to complete the job.
