i have 7.75x3.50 bricks i will be using to build a 9x14 patio, how many bricks will i need
9' x 14' = 9(12) x 14(12) = 18144 sq in
each brick is 7.75 x 3.5 = 27.125 sq in
18144/27.125 = 668.9 ~=669 bricks if there is no space between them (mortar sand etc) NOTE : some of the bricks will need to be cut as they will not fit evenly into the 9x14 dimension....I would order extra bricks....example: 700)
