Wall area is the room perimeter times the ceiling height, here about 352 square feet for an 8 foot ceiling. One gallon covers 350 to 400 square feet per coat, so we use 375. Primer and dark colours can need more.

How much paint for a 10 by 12 room?
A 10 by 12 foot room with 8 foot walls has about 352 square feet of wall. At two coats that is roughly 2 gallons.
