To determine the square footage of X, you'll need to know the dimensions of the area in question. Square footage is calculated by multiplying the length by the width of the space (in feet). If you provide the specific dimensions, I can help you calculate the square footage.
1 ft x 1 ft = 0.092903 square metres.
42 ft x 30 ft = 1,260 square ft1 yd = 3 ft(1 yd x 1 yd) = 1 square yd = (3 ft x 3 ft) = 9 square ft.1,260 square ft = (1,260 / 9) = 140 square yards
75-ft x 12-ft = 900 square feet
The square root (5 ft x 5 ft) = 5 ft.
16 ft x 7 ft = 16 x 7 square ft = 112 sq ft
1 ft x 1 ft = 0.092903 square metres.
42 ft x 30 ft = 1,260 square ft1 yd = 3 ft(1 yd x 1 yd) = 1 square yd = (3 ft x 3 ft) = 9 square ft.1,260 square ft = (1,260 / 9) = 140 square yards
75-ft x 12-ft = 900 square feet
The square root (5 ft x 5 ft) = 5 ft.
16 ft x 7 ft = 16 x 7 square ft = 112 sq ft
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.
10 ft x 8 ft = 80 square feet.
30 x 34 = 1,020 square feet
There are 324 square feet
18-ft x 11-ft = 198 square ft
100-ft x 200-ft = 20,000 square feet
(12ft x 12ft) square =144 sq ft. 12ft x (12 ft square) is 1728 cu ft.
