Best Answer

8 in x 4 in = 2/3 in x 1/3 in = 2/9 sq ft.

Area to be covered = 114 sq ft

so minimum number of bricks required = 114/(2/9) = 114*(9/2) = 513.

The exact number will depend on details of the shape to be covered, since that will determine how many (if any) bricks need to be cut/broken. That, in turn will determine how much wastage there could be.
