Assuming you lay them all the same way.... 4x8 = 32, area of a brick. 6x24 = 144, area of the walkway. Now, the walkway is in square feet, so we need to multiply by 144 to change it to square inches. 144 x 144 = 20,736. Divide this by the area of the brick. 20,736 / 32 = 648 So you need 648 bricks to cover the entire walkway.
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.
Amount of bricks needed: 12(6*24)/(4*8) = 54
My guess is that you would need approximately 650 bricks. The math is as follows: 6 feet (72 inches) by 24 feet (288 inches) equals a total area of 20,736 inches. If your brick area is 4 x 8 inches (32 inches) you would need 648 bricks.
The walk is 6*24 = 144 square feet. Each brick is 1/3 (4 inches) by 2/3 (8 inches) feet. So a brick is 1/3 * 2/3 = 2/9 square feet. 144 / (2/9) = 144 * (9/2) = 144 * 9 / 2 = 72 * 9 = 648 bricks
A 12 x 12 inch brick is 1 square foot. A 20 x 20 (foot) patio is 400 square feet, so you would need 400 bricks.. this assumes you are butting the bricks fairly tight, not leaving large seperations between them, etc...
A single layer will require 144 bricks.
648 bricks to build the walk

the answer to this question is 648 Bricks.
the brick height is 9"(inch)
The area of one 4 inch by 9 inch brick is 36 square inches.The area in square inches of 200 square feet of wall is 28800 square inches (200 x 12 x 12).The number of 36 square inch bricks to cover an area of 28800 square inches is 800 (28800/36).
It is not possible to answer the question without information about the measurement units used for 40x40. And it is difficult to guess because a 40 inch x 40 inch brick would be huge whereas a 40 millimetre x 40 millimetre brick would be tiny.
You don't say how high the wall is.
