To calculate the area of the patio in square inches, we first convert the dimensions to inches (12 ft = 144 in, 14 ft = 168 in). The patio's area is therefore 24,192 square inches. Each 8-inch paving stone covers 64 square inches, so divide the total area by 64 to find that you'll need 378 paving stones to pave the patio.
There are 10.857 stones in 152 pounds.

Assuming you don't want to cut and paste, then 4 x 11 = 44
This needs more information to supply a "best" answer. however.. assuming you mean 144 sq feet of patio and your stones are 16 inches x 20 inches. then accuratly you will need 66 stones. add at least 10% for cutting waste then i'd go buy 80 maybe 85.
