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.
115 should do it!
About 14 bricks should do it.
Gee, a square foot is 12x12, difficult problem.
1,350 of them.
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.
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".
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...
Each brick has an area of 1ft x 1ft ie 1 sq foot. So you would need 308 bricks.
The answer will depend on the shape of the patio. If it curved then some bricks will need trimming and that will result in wastage and so a larger number of bricks will be required. Also, if the patio leaves a small fractional amount after a whole number of bricks, you will need a lot more bricks. As an extreme example, if the patio is 8 cm*625 metres then you will need 3125 bricks. However, if the shape is convenient, you will require 2500 bricks.
If the bricks are in feet then 51/2 bricks would be needed.
Technically, 2.6388888888888 etc. but 3. I'm assuming the brick is 12x12 feet here as that is the only unit you have mentioned...
It depends on the dimensions used for the measurements of the bricks. If the bricks are 6 ft x 9 ft (and there is nothing in the question to indicate otherwise), then 6 bricks will be enough.
A 12" x 12" brick covers an area of one square foot. Assuming your patio is 396 square feet, then you would need 396 bricks. However, you will almost certainly have to cut some bricks to fit them into whatever shape your approximately 20' x 20' patio will be, so you should figure on needing a few more. The rule of thumb is to order what you need plus 10% extra, but make sure you can return the unused bricks. Area covered by 12x12 inch brick is 144 square inches. That is 1 square foot. Total area of the patio is 396 square foot. Number of bricks required = 396/1 = 396 bricks. Source: www.icoachmath.com That gives you the extra ten percent you'll need to compensate for cutting, breakage, etc.
around 220 but remember you my have waste for cuts or damaged pieces.
Is that 144 square feet, as in 12' x 12'?If that is the case, you would need a minimum of 81 bricks. If the patio is indeed square, or 12' by 12', each side is 144", or 9 16" bricks. 9 x 9 = 81 bricks.If the patio is not square, you may need extra bricks on one or both sides if the width is not evenly divisible by 16 inches.
You would need 309 tiles plus about 40 +/- more for waste.
Hello Questioner, The total would be 108 assuming that no spaces between bricks is catered for. It is assumed that the brick dimension is in inches. Obviously there will be some mortar between bricks but on the whole I would stick to the figure, mainly to allow for breakages etc. The calculation was as follows: One brick is 32/144 square feet, therfore 24 square feet will require 24 divided by 32/144 which equals 108. The 144 is derived from the number of square inches in a square foot. It does not matter how the 24 square feet is made up. Could be 2x12, 3x8, or 4x6 it would still require the same number of bricks. Best regards. JF
each brick covers 16 x 16 = 256 sq in = 1.778 sq ft 190/1.778 = 107 bricks
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.
Each brick is 27 square inches. 27*434=11,718 square inches of bricks.
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.
Brick is 3" x 8" = 1/4' x 2/3' = 2/12 = 1/6 square feet To fill 75 square feet you will need (75)/(1/6) = 75 x 6 = 450
