You need 67 by the math but to account for edges you will need 81 pavers
78.47 Pavers
You would need exactly 36 pavers.
You would need a total of 5 pavers - since the area to be covered is just under 4.25 tiles. Wrong answer!

12 inch * 12 inch = 1 ft * 1 ft = 1 sq ft. Therefore, a minimum of 72 pavers are needed. That answer assumes that the shape is well behaved and the pavers do not need to be cut. Or that, if they are, all the offcuts are used. Pavers may need to be cut/trimmed if, for example, the area is circular.

There are 12 inches in a foot. Therefore the 24 inch pavers are 2 foot pavers each with an area of 2*2 = 4 square feet. The area to be paved measures 10*2 = 20 square feet. Therefore you will need 20/4 = 5 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.

Assume they are 9 inch x 6 inch pavers. The area of each paver is 9*6/144 = 3/8 sq feet Area to be covered = 144 square feet So number of pavers required = 144/ (3/8) = 384 That is the minimum number required if the area to be covered is "well behaved". If the area is not an exact number of pavers long/wide, of if there are curves you will have to cut some pavers and, unless all the offcuts can be used, you will require more than 384.
