There are calculators that estimate, but you need to determine the pavers you want, because the Sq. Ft. differs from one paver type to another, depending on thickness and paver dimensions. Most brick yards will tell you the Sq Ft when you find a suitable paver. http://www.whiteblockcompany.com/pavers-...

A standard-size pallet is 40 x 48, which equates to a surface area of 1,920 square inches. Based on these measurements, roughly 113 bricks are needed to cover the pallet. If each brick weighs 4.3 pounds, the pallet of bricks weighs 486 pounds with just a single layer of bricks on it. However, this example does not account for the weight of the pallet itself.
