280 square feet is 40,320 square inches.
Remember there are 12 inches in 1 ft (linear) So 12 inches x 12 inches = 144 sq. ins in 1 ft x 1 ft = 1 sq.ft. (area) So in 1 sq.ft. there 144 sq. inches. So multiply 1008 sq.ft. by 144 sq .inches = 145152 sq.ins,
four ft. x four ft. = sixteen sq. ft. example: 4ft. x 4 ft. = 16 sq. ft.
464.52 sq meters.
That would be 68.87 acres.
It is not entirely clear what the question is asking but the areas can be configured as80000 sq ft = 400 * 200 sq ft leaving an area of 400 * 200 sq ft, then 40000 sq ft = 400 * 100 sq ft leaving an area of 400 * 100 sq ft, then 10000 sq ft = 100 * 100 sq ft leaving an area of 300 * 100 sq ft, then 5000 sq ft = 100 * 50 sq ft leaving an area of 250 * 100 sq ft.
280 sq ft = 26.01 sq metres, approx.
450 sq ft = 64,800 sq inches.
2,000 sq ft = 288,000 sq inches.
Answer: 280 ft² = 26.0128 m²
4.5 inches by 36 inches is 1.125 sq ft
443 sq inches is 3.07639 sq feet.
2 sq ft = 2*144 = 288 sq inches.2 sq ft = 2*144 = 288 sq inches.2 sq ft = 2*144 = 288 sq inches.2 sq ft = 2*144 = 288 sq inches.
1 sq ft = 144 square inches
110 inches x 60 inches = 6600 square inches / (144 sq in / sq ft) = 45.833 sq ft
1 sq ft = 1 ft * 1 ft = 12 inches * 12 inches = 144 sq inches.
One 16 * 16 square metres should be more than sufficient! If you meant 16 * 16 inches - why didn't you say so? 280 sq ft = 280*144 sq inches = 40320 sq inches 40320/(16*16) = 157.5 So 158 tiles would be needed. That is the mathematical answer. This assumes that all off-cuts are used and that there is no wastage.
That depends on the shape of the 280 sq. ft. area. For example, if it is a rectangle 1 foot by 280 feet, you couldn't fit a single tile into it (I assume you mean square tiles that are 20 inches on each side) because 20 inches is more than 1 foot. But assuming the area is a rectangle who sides are a multiple of 20 inches (or at least one is), we can get a pretty good estimate by converting to square inches. A sq. ft. is 12 x 12 or 144 sq. in. So 280 sq. ft. = 280 x 144 = 40,320 sq. in. Now the area of one tile is 400 sq. in. Dividing 40,320 by 400, we get 100.8. So with a suitable shaped area, we could cover most of it with 100 tiles, but there would be 320 sq. in. left over. 101 tiles would more than cover that much area, but again, to cover a given area of 280 sq. ft. with 101 tiles, the area must have a suitable shape.
