First find the area of each wall. This is length*width which would be 12*8.5=102. There are four walls in the room because it’s a square so that would be 102*4=408. So the total area you need to paint is 408ft one gallon will cover 75ft so 408/75=5.44 gallons of paint.

If it is 12ft wide and 8 feet 5 inches tall it would be 101 sqft per wall.
101 x 4 = 404
75 x 6 = 450
So it would be 6 gallons of paint.
If it is 8 1/2 feet it would be the same amount of paint.
102 x 4 = 408
75 x 6 = 450
So 6 gallons of paint.
Hope it helps!
