you would find the area of the bricks... 4x8=32... then divide 550 by 32 which equals 17.1875... the answer would be 18 because you would need that .1 of a brick so you could not round down

Math says 4 1/2 4"x8" bricks are needed to cover 1 sq. ft. So 9 bricks will cover 2 sq ft. That needs to happen 500 times so you need 9x500 or 4500 bricks sized 4"x8" to cover 1000 sq ft.
It depends on the size of the bricks and their orientation.

To determine how many bricks are needed for 144 square feet, first, calculate the area of a single brick. For example, if a standard brick measures 7.5 inches by 3.5 inches, the area is approximately 0.11 square feet. Dividing 144 square feet by the area of one brick (0.11 sq ft) gives about 1,309 bricks. However, it's important to account for mortar space, so it's advisable to add 10% more, resulting in roughly 1,440 bricks needed.
