For square footage (area) you only have two measurements. So a carpet 4 ft x 4 ft has a square footage of 16 square feet. And a carpet of 4 ft x 8 ft has a square footage of 32 square feet.
Three measurements like 4 ft x 4 ft x 8 ft give you cubic footage, or volume. So the volume of a container that size would be 128 cubic feet.
A 4x8 sheet of plywood covers 32 square feet. This is calculated by multiplying the length (4 feet) by the width (8 feet) of the sheet. Therefore, the total square footage of a 4x8 sheet of plywood is 32 square feet.
8-ft x 4-ft = 32 square feet
To find the square footage of a rectangle, you multiply the length by the width. In this case, the rectangle is 2 feet by 4 feet. So, 2 feet multiplied by 4 feet is equal to 8 square feet. Therefore, the square footage of a 2ft x 4ft rectangle is 8 square feet.
A 53-foot trailer holds 3816 cubic feet of air (8' wide by 9' high by 53' long). The floor space on an 8' x 53' trailer would be 424 sq. ft.
10 ft x 8 ft = 80 square feet.
4' * 8' = 4*8 sq ft = 32 sq ft
Square footage of the room = 14 ft * 8 ft = 14*8 sq ft = 112 sq ft.
48
The area of a circle is pi*(radius)^2. If the 8 ft is the diameter, the area is pi*(4 ft)^2~=50.27 ft^2 (ft^2 is square feet)
8 ft X 6 ft = 48 sq.ft. ( NOT ft^(2)).
240 square feet
Area = 12 ft * 8 ft = 96 sq ft.
To calculate the square footage of a rectangle, you multiply the length by the width. In this case, 4 feet multiplied by 8 feet equals 32 square feet. So, a 4 ft x 8 ft area would be 32 square feet in total.
8 square feet
32
Assuming the room is 8 ft by 10 ft (the question does not say so), the area would be 8*10 = 80 square feet
1'4 * 8' = 11/3' * 8' = 102/3 sq ft.
