15 feet x 15 feet = 225 square feet.
The floor and ceiling are each 20 square feet. In order to know the area of the walls, we would also need to know the height of the ceiling.
To find the area of a room, multiply the length times the width. 20 X 20 equals 400 sq ft.
20 x 20 = 400 (square meters).
400 (20x20) square inches is 2.78 square feet.
2.78 square feet.
400 square feet (20 x 20 = 400)
If that is 20ft by 20ft then there are 400 square feet

A typical 2 car garage is 20x20 which equals 400 square feet
70 square feet on the ceiling, and another 70 square feet on the floor. We don't know how many square feet on the walls unles we know the height of the ceiling.
120 square feet on the floor, and another 120 square feet on the ceiling. We can also calculate the square feet on the walls if we know the height of the ceiling.
120 square feet on the floor, and another 120 square feet on the ceiling. We can also calculate the square feet on the walls if we know the height of the ceiling.
A 20' x 18' ceiling comprises 33.45 (33.4450944) square meters.
1070 square feet is 154080 square inches. (1 square foot is 12x12 or 144 square inches.)a 20x20 inch tile is 400 square inches.So the question could be restated as "how many 400 square inch tiles does it take to cover 154080 square inches?"154080 / 400 = 385.2
15 feet x 15 feet = 225 square feet.
