About 14 bricks should do it.

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).

If you lay out your bricks, 3 wide and 3 long, you'll get an area 12 inches x 24 inches. So every 9 brick, you'll cover 2 square feet. So 4.5 bricks per square feet X 396 square feet = 1782 bricks. Add a few for damage and waste, at least 1800 bricks for the patio you describe, maybe a few extra if the dimensions don't come out even. The bricks each cover an area of 32 square inches (4 x 8). The patio is 396 square feet. Since there are 144 square inches to the square foot, that means the patio is 396 x 144 = 57,024 square inches in area. Dividing that by 32 square inches per brick yields 1,782 bricks, exactly what was calculated above. First we shall convert 396 square feet into square inches. 12 inches equal to 1 foot. So, 1 square foot equal to 144 square inches Therefore, 396 square feet equals to 57024 square inches. Area of the brick = Length * Width = 4 * 8 = 32 square inches. Number of bricks required to cover 57024 square inches is 57024/32 = 1782. So, you need 1782 bricks. Source: www.icoachmath.com If you measured your area as 37 square metres and each brick was 10 cm by 20 cm then each brick is 0.1 * 0.2 square metres = 0.02 square metres. Number of bricks = 37/0.02 = 1850.

Multiply 4 time 8 to get 32 square inches for each brick, then divide 32 by 144, the area of a square foot, to get 0.22222etc, then divide 175 by the 0.22222 to get 787.5 or 788 bricks if you can only have whole bricks.

The first step is to convert the total patio area to inches so we are working with the same units. 100sq ft = 14,400 sq inches. Now we need to calculate the number of square inches each brick takes up. Answer: 36 sq in. Now we just divide the total square inches of the patio by the square inches taken up by each brick: 14,400/36 = 400 bricks. It will take 400 bricks to make a 100 square foot patio.

If a standard brick is 4 inches wide by 8 inches long, you'd need 648 of those bricks. Here's the way you'd calculate it: First, since your bricks are measured in inches, I'd convert your 6 foot by 24 foot measurements from feet to inches. Since there are 12 inches per foot, 6 x 12 = 72 inches and 24 x 12 = 288 Then you can calculate the total area you are going to be laying brick in (in inches), so multiply 72 x 288 = 20736 square inches The area of each of your bricks is 4 inches by 8 inches, so 8 x 4 = 32 square inches per brick If your total area you want to brick is 20736 square inches, and each brick is 32 square inches, just divide 20736 by 32... which gives you 648. :)

Of course it depends on the size of the brick. But you can still do it by the following steps. 1. Let y = square inches of one brick (compute length X width). 2. # bricks = 144 / y ( the number of square inches in a sq. foot divided by size of a single brick) For example suppose a brick is 2 by 8, then y = 16. 144/16 = 9 so you'd have 9 bricks in a square foot. If you think about it, lay the 9 bricks side by side they'd cover an area that is 18 x 8 =144, the same number of inches in a 12 in x 12 in area. If you are going to use mortar between the bricks, remember to allow for that in your computation of the brick size..

To do this you would need to know the area of a brick and the area of the wall. Then you divide the area of the wall by the area of a brick. There are approximately 60 bricks per square metre.

The question, as stated cannot be answered. You need to know two dimensions of the bricks to find the area of each brick, convert that area into square feet (if necessary) and then divide 256 by the area of each brick. Bricks are not usually square so it would not be appropriate for me to assume that the bricks are 16" by 16".
