    If your bricks are laid with the long side making up the width and the short side making up the length:

    6 feet is 72 inches, so you would need 9 bricks across.

    24 feet is 288 inches, so you would need 72 bricks down.

    9 x 72 = 648 bricks

    OR

    When you convert feet to inches and find the area of your walk, 72 x 288 is 20736 square inches.

    Each brick is 32 square inches, so when you divide 20736 by 32 you'll get 648 bricks

    a brick is 4 in x 8 in or 32 sq in.

    6 ft is 72 in

    24 ft is 288 in

    72 in x 288 in is ? sq in

    ? divided by 32 sq in is the number of bricks needed

    Think about it. 1 foot = 12 inches

    You will get it, just draw it out on paper.

    Good Luck.

    Use it before you lose it.
