The way to calculate the number of bricks is to calculate the area of the walk and then divide by the area of a single brick. One very important point - the same units must be used for both areas (whether you choose inches, feet or anything else, it doesn't matter, you will get the same answer).
The area of the walk is 6x24 square feet and, as there are 12 inches in a foot, this equals (6x12)x(24x12) square inches. This equals 20736 square inches.
The area of a brick is 4x8 = 32 square inches.
Dividing one by the other, the number of bricks required, N, is given by:
N =20736/32
= 648 bricks exactly.

18 across and 36 long
Assuming you actually require 24 feet long and 6 high as a 6 wide wall will be only 4 inches high. The bricks required without cutting contingency is 803
You need 648 bricks. Convert 6 feet into 72 inches times by 24 feet converted to 288 inches which equal 20,736 square inches. A 4 x 8 inch brick is 32 square inches. Now take 20,736 inches and divide that by 32 which equals 648.
648 bricks to build the walk
648
the answer to this question is 648 Bricks.
There is no information on the heights of either the bricks or the wall!
648
no.of bricks =144 x12x144 X12 /(4x8) =93312
You don't say how high the wall is.
648
A single layer will require 144 bricks.
Amount of bricks needed: 12(6*24)/(4*8) = 54
18 x 72 = 1296
