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.

A "45-ft vegetable garden" seems to be so skinny that perhaps it could be surrounded by a single row of 90 bricks.

648 Because: There are 12 inches in 1 foot. So 1ft wide is 3 bricks (12/4=3) and 1 ft long is 1.5 bricks (12/8 = 1.5). So 6ft x 3 = 18 bricks, 24ft x 1.5 = 36 bricks. To get the area: 36 bricks x 18 bricks = 648 Bricks.
