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.
Gee, a square foot is 12x12, difficult problem.
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.
About 240 three inch by eight inch bricks would be need for create a ten foot by four foot patio. It would be preferable to purchase another 24 or 10 percent more for wastage.
you would need 12...
36 tiles. I would hire a tiler if I was you, this doesn't sound like your 'thing'
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.
6 inches is half a foot so it takes four 6 by 6 inch bricks to make one square foot. 348 x 4 = 1392. So you'll need 1392 bricks.
needs more information to be accurately answered.
12inch x 12inch is 1ft x 1 ft=1 square foot You need 100 patio stones
225 bricks. 16in * 16in = 256 sq. in. 20ft = 240in. 240in * 240 in = 57,600 sq. in. 57,600 sq. in. / 256 sq. in. = 225. 225 bricks is your answer.
12" x 12" = 1 square foot, so you need 452 of them.
80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
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.
144 square feet
12X12=1 Square Foot of tile. You would need 49 Square Feet of tile.
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.
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".
432 x 12 inch x 12 inch bricks for an area 18 feet x 24 feet
12 time 12 inches = 1 square foot (as there are 12 inches in a foot) 10 times 8 feet = 80 square feet 80 square feet divided by 1 square foot = 80 pavers.
A 12x12 inch paver is one square foot. So you would need 240 square feet.
