Question

Rochelle is painting her loft teal. There are three walls

that need to be painted. The first wall has dimensions 8
feet by 16 feet. The second wall has dimensions 8 feet
by 21 feet, and the third wall is 8 feet by 11 feet. She
wants to paint two coats. If a gallon of paint covers 350
square feet, how many gallons will she need?

Answer 1

(8*16)+(8*21)+(8*11)= 384ft^2
Then you divide by the gallon of paint

384/350 and get approx. 1.1 gallons of paint
