Question

Holly wants to paint the walls and ceiling in her new bedroom

before hanging any pictures or posters. She measures the room
and discovers it is 18 feet long by 15 feet wide with 10-foot
ceilings. The paint she selected is $25.00 per gallon. Each gallon
of paint covers 200 square feet. How much will Holly budget for
paint?

Answer 1

$125.00

Explanation:

4 walls (2 at 18 foot and 2 at 15 foot). height of each wall = 10 foot.

total area of 2 wide walls = 2 (10 X 15) = 300 square foot.

total area of 2 long walls = 2 (10 X 18) = 360 square foot.

area of ceiling = 18 X 15 = 270 square foot.

total area = 930 square foot.

200 square foot for one gallon of paint.

she will need 930/200 = 4.65 tins of paint = 5 tins.

one tin costs $25.

she will have to budget 5 X 25 = $125.00
