About 14 bricks should do it.
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...
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.
A lot !!
115 should do it!
between 1100 and 1200 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.
1,350 of them.
2700 4" x 8" bricks (plus 10% waste)
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".
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.
Our patio needs replacing. How difficult is it to construct a patio with brick pavers?
81 bricks.12 feet times 12 inches per foot = 144 inches.144 inches divided by 16 inches per brick = 9 bricks in length/width.9 bricks (length) times 9 bricks (width) = 81 bricks.
Gee, a square foot is 12x12, difficult problem.
Technically, 2.6388888888888 etc. but 3. I'm assuming the brick is 12x12 feet here as that is the only unit you have mentioned...
Each brick has an area of 1ft x 1ft ie 1 sq foot. So you would need 308 bricks.
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.
this depends on the size of the bricks. Assuming 4x9 inch bricks then 3.14 x (15/2)2 x 1212 = 25434 sq inches 1 brick is 4 x 9 = 36 sq in. 25434 / 36 = 706.5 bricks but there would be some waste from cutting the bricks to make a circle.
Assuming the 12x12 bricks are 12 feet on each side, those are 144 square feet. The patio itself is 76 square feet. Unless you made a typo, not even one of those bricks is going to fit on the patio; you end up with about 0.5278 bricks.
