(40 feet)(28 feet) = 1120 square feet.
Then the surface area of the solid would be measured in square feet
Surface areas are measured in square units, such as square inches, square feet, square meters, etc. To determine the surface area, first ensure you have the length and width of the rectangle expressed in the same units (both in inches, both in feet, etc.), then multiply the length by the width: 2 feet x 3 feet = 6 square feet
I suppose you mean, "a square that has a surface of one acre". An acre has 43,560 square feet; to get the length of a square of that area, take the square root of that. The result is about 208'9".I suppose you mean, "a square that has a surface of one acre". An acre has 43,560 square feet; to get the length of a square of that area, take the square root of that.

Surface area = 4*pi*72 = 615.752 square feet to 3 dp
The floor is (8 x 12) = 96 square feetThe ceiling is also . . . 96 square feetTwo walls are (8 x 8) = 64 square feet eachThe other two walls are (8 x 12) = 96 square feet eachThe total inside surface area is (2) x (96 + 64 + 96) = 512 square feet(including the area of the door, hatch, etc.)
The floor's area is: 1,296 square feet.
The area of the floor is 1296 square feet.
30' x 30' = 900 square feet.
The surface area of planet Earth is 196.9 million square miles or 5,489,256,960,000,000 square feet.
Exactly 1200 square feet!
The surface area is 1,020 square feet.
The area of the ceiling is 368 square feet. The area of the floor is also 368 square feet. In order to find the area of the walls, we need to know the floor-to-ceiling height of the room.
357 square feet
288 square feet
18 square feet.
The area of the ceiling is 375 square feet. The area of the floor is also 375 square feet. If we knew how low the floor is below the ceiling, we could also tell you the area of the walls.
15'x33' (495 square feet) = 55 square yards of floor.
