On a purely mathematical level, you should need 123.75. But if you actually want to put down your own patio, it might make sense to buy a few (or more than a few) extra just in case.
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.
To determine how many 16x16 pavers are needed for a 5x5 patio, first calculate the area of the patio and the area of one paver. The patio area is 5 feet x 5 feet = 25 square feet. Each 16x16 paver covers 2.67 square feet (16 inches = 1.33 feet, so 1.33 x 1.33 ≈ 1.78 square feet). Dividing the patio area by the paver area, you need approximately 10 pavers (25 ÷ 1.78 ≈ 14). Therefore, you would need about 15 pavers to cover the patio area completely.

Area of 1 paver = 16*16 = 256 square units. Area of patio = 20*20 = 400 square units. Number of pavers required = Area of patio/Area of paver = 400/256 = 1.5625 So 2 pavers will suffice.

If you mean 12" x 12" (= 1 ft²) then you will need 224 pavers.
