minnie is painting her walk in closet. Each gallon covers 275 square feet. The floor is 9ft wide and 7ft long. The roof is 8ft high. How many gallons of paint would she need to cover her closet with to coats of paint.

Answer 1

do the floor and ceiling get painted?
And that is "two coats"
You have
two walls 9*8
two walls 7*8
floor and ceiling 9*7
add up the areas you want to paint, and then
multiply the area by the number of coats
gallons used = area*coats/275
