All you need to do is multiply 4 by 8. The answer is 32 tiles. Buy a few extra in case of breakage.
5x8=40sq.inches 12x20=2880. sq. inches divide 2880 divided by 40 = 72 pavers
Area of each paver = 4"x9" = (1/3)'x(3/4)' = 1/4 sq ft. Number of pavers required = Total Area/Area of Each Paver = 500/ (1/4) = 2000 pavers. In real life, though, the number of pavers will depend on the shape and exact dimensions of the area, how many pavers you need to cut or trim, what the wastage is.
158 of them. Get extra for breakage.
124 but get more for cutting the edges depending on design
6x3 would require 2 pavers by 4 pavers to make a square foot which is 8 pavers per square foot. 240 pavers. That's only a 5 foot by 6 foot square.
576 should do it.
216
272 Get 300 to be safe.
One should do it!
Depend on the size of the pavers.
144
One should be more than enough!
264 of them. Get extra for breakage.
If both items are measured in inches or feet, the half is the answer. Without more info. this cannot be answered.
144 Get 160 to be safe.
72 Get 80 to be safe.
The number of pavers you will need will be basd on the size of your patio. You should measure the square feet of your patio.
