In theory the answer is 800 tiles but this assumes that the area is "well behaved" and, if not, that you are prepared to use all the offcuts to fill bits in mosaic-style. A shape which in 17 inches wide, for example, will require a lot more pavers.
The paver will cover 54 square inches. You have 43,200 square inches to cover. So you will need 800 pavers, plus some for breakage.
It will take four pavers to cover one square foot. You will need 720 pavers.
You'll need 90 of them because 80/(16/12 times 8/12) = 90
67 of them.
20 feet, 1 inch
It depends how thin the cubic feet are. If they are 1 foot thick: 21,000 cubic feet. If they are 3 feet thick: 63,000 cubic feet will cover 21,000 square feet.

128; each paver is half a square foot.
200(square feet)x12(inches in a foot)=2400(inches)8(inches)x8(inches)=64(inches)2400(inches)÷64(inches)=37.5(pavers)37.5 pavers (if you need whole pavers, 37)
That will depend on the size of your pavers. You have 22,932 square inches to cover.
4.5 pavers will cover 1 sq foot. So 4.5 x 360 =1620 pavers
A 12x12 inch paver is one square foot. So you would need 240 square feet.
Assuming the question is about pavers that are 12 inch x 12 inch, then each paver covers 1 sq foot and so 150 pavers would be required. However, this also assumes that there is no wastage at all and that there are no breakages.
1 square foot = 144 square inches100 square feet = 14,400 square inches8-in x 4-in = 32 square inches14,400/32 = 450 pavers
18" is 1.5', so we can discover the number of square feet in one paver by multiplying 1.5 x 1.5 = 2.25 square feet. To fill an area of 14' x 14', or 196 square feet, you would need 196 / 2.25 = 87 pavers, with room for .11 pavers left over. So to cover it completely, 88 pavers would do the trick.
