The "square footage" is usually called the "area".
A room that measures 3-ft long and 3-ft wide has
-- 9 square feet on the floor
-- 9 more square feet on the ceiling
-- more square feet on the walls, but in order to count those,
you have to know the height of the ceiling above the floor.
3*5 = 15 square feet.
Square footage of the room = 14 ft * 8 ft = 14*8 sq ft = 112 sq ft.
if you want the square footage, 15 ft x 20 ft is 300 square feet
To calculate square footage, you multiply the length by the width of the room. So, if the room measures 10 ft. by 18 ft., your total area is 180 sq. ft.

36in is 3ft and 48in is 4 ft so 3x4 is 12sqft.
160 ft. squared
To find the square footage, multiply 3ft by 5ft. 3 x 5 - 15 sq ft
72 sq. ft
270 sq ft
18 ft X 20 ft = 360 Square feet
