I'm going to assume that you mean the room is 8-ft high.
Floor . . . 480 square feet
Ceiling . . . 480 square feet
Two walls . . . 160 square feet each
Other two walls . . . 192 square feet each
Total square feet of surface area inside the room = (480 + 480 + 320 + 384) = 1,664 square feet
If you're using this number for paint, remember to take off the area of
doors, windows, baseboard heaters, electrical outlets, etc.
21 x 11 = 231 -- There are 231 square feet on the floor. -- There are 231 square feet on the ceiling. -- There are a lot more square feet on the walls, but in order to calculate them, you need to know the height of the room.
what are the dimensions of the room? Is it square? Assuming it's square, 32ft perimeter means 8 foot walls. 8 foot walls means 64 square feet of flooring. Assuming it's a rectangle with the long wall of 10 feet and the short wall of 6 feet, then it's 60 square feet of flooring.
165 square feet
130 square feet
Length mutiplied by width. For example if you a room that is 12 foot by 10 foot then the room is 120 square feet.
21 x 4 = 84 -- There are 84 square feet on the floor. -- There are 84 square feet on the ceiling. -- There are a lot more square feet on the walls, but in order to calculate them, you need to know the height of the room.

Floor and ceiling . . . (10' x 10') = 100 square feet eachFour walls . . . . . . . . (10' x 8') = 80 square feet eachTotal area inside the room = 2 (100) + 4 (80) = 520 square feet

Floor = 100 square feetCeiling = 100 square feetWalls = we can't calculate the walls without knowing the height of the ceiling
To calculate the amount of drywall needed for a 14 by 20 foot room with 9-foot walls and a ceiling, first determine the area of the walls and ceiling. The walls' total area is (2 \times (14 + 20) \times 9 = 612) square feet, and the ceiling area is (14 \times 20 = 280) square feet. Adding these together gives (612 + 280 = 892) square feet. Drywall typically comes in 4x8-foot sheets, so you would need about 28 sheets (since each sheet covers 32 square feet).
To calculate the square footage of a room, you multiply its length by its width. For a 10x14 foot room, the calculation is 10 feet × 14 feet, which equals 140 square feet. Therefore, the room has a total area of 140 square feet.
144 square feet.
