Question 204059: A room measures 15 ft by 19 ft. The ceiling is 10 ft. above the floor. The door is 3 ft. by 7 ft. A gallon of paint will cover 78.2 ft2. How many gallons of paint are needed to paint the room (including the ceiling and not including the door). Round your answer up to the next whole number.
Thank you for your time and your help.

You can put this solution on YOUR website! Areas are; ceiling = 15*19= 285
,,,,,,,,,,,,,door = 3*7 = (21)
,,,,,,,,,,,,,wall1 = 15*10 = 150
,,,,,,,,,,,,,wall2 = 15*10 = 150
,,,,,,,,,,,,,wall3 = 19*10 = 190
,,,,,,,,,,,,,wall4 = 19*10 = 190
.
,,,,,,,,,,,,TOTAL = 944
.
944 ft^2 * 1 gallon/ 78.2 ft^2 = 12.07 gallons
.
Problem says to round up to 13 gallons,,,,but this is so slightly over
it would be a waste to buy that extra.
