Frank would need two gallons of maroon painting and one gallon of white painting to paint all his room.

How much white painting is required?

Area of the ceiling:

  • 12 feet x 12 feet = 144 squared feet

Assuming the floor has the same area, the total area for the floor and ceiling is 288 square feet.

Area of the door:

  • 3 feet x 7 feet = 21 feet

Total area in white 144 feet + 21 feet = 165 square feet

Total of gallons

1 gallon equals 400 square feet, which means only one gallon of white painting is required.

How much maroon painting is required?

Area of one wall:

  • 12 feet x 10 feet = 120 feet
  • 120 feet x 4 walls = 480 square feet
  • 480 square feet - 21 feet (door) = 459 square feet

Considering 1 gallon equals 400 square feet, a total of 2 gallons would be required.
