needs more information to be accurately answered.
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...
144
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.
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.

Gee, a square foot is 12x12, difficult problem.
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.
It depends on the size of the 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.
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.
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".
1,286 more or less. Some cuts will probably need to be made and there will be some waste.
First determine the square footage occupied by the patio ... 15 x 8 = 120 sq. ft. Next determine the square footage of your bricks. They are 24 inches wide by 24 inches long ....OR 2 feet wide by 2 feet long (pretty BIG bricks !) .... 4 sq. ft. each. IF you can cut your bricks without shattering them, you would need a minimum of 120 divided by 4 = 30 bricks. If you shatter any, you might need a few extra. Note that you need to cut the bricks because each is 2 feet wide and one of your dimenstions is an odd number (15). So, you could use 7 whole bricks, and one half brick to cover the 15 feet on that side of the patio. You'd have to cut 2 bricks in half to fill the last foot down the 8 foot side. Hope this helps.
