**DrBob222**, Tuesday, October 2, 2007 at 11:21am6' wide x 12 in/ft = 72 inches

72 inches/4 inches/brick = 18 bricks needed for the 6 foot side.

24' long x 12 in/ft = 288 inches.

288 inches/8 inches/brick = 36 bricks needed for the 24 foot side.

18 bricks wide x 36 bricks long = ?? bricks total to cover the area.
