Error in my post:

The walls and ceiling of a room 12 feet x 16 feet x 8 feet with the same windows and doors are to be painted.

add 16 x 12 = 192
391 + 192 = 583
583 / 300 = 1.943 gal

Calculate amount of paint required.

Just deduct the are of windows and doors from the total area, then you can get the area that can be painted then calculate the amount of paint
