You are painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall. You need two coats of paint . If a gallon of paint covers 400 square feet and cost $53 per gallon, how much will you spend on painting this room?
1 answer:
Answer:
$424
Step-by-step explanation:
Find area of all surfaces to be covered
20 x 30 = 600 ceiling
10 x 20 = 200 x 2 = 400 two walls
10 x 30 = 300 x = 600 other two walls
Assume no doors
total area is 1600 square feet
multiply by 2 because you are doing two coats
3200 total area to be covered
3200/400 = 8 gallons of paint x $53 = $424
