10' by 10' with 8-ft ceilings: -- Floor = 100 square feet -- Ceiling = 100 square feet -- Each wall = 80 square feet Total interior surface area of the room = (2 x 100) + (4 x 80) = 520 square feet. (Less windows, recessed light fixtures, doors, electrical outlets, etc.)
You have to multiply the two numbers to get the square footage. In this problem the results will be 6,400 square feet.
