46 bricks; add a few more for waste and cutting

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.

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

12x13/12=13

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.

432 x 12 inch x 12 inch bricks for an area 18 feet x 24 feet

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.

19 1/2 tiles plus you want to add 10% for waste

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.

It depends on your climate and what the patio cover is made of.

48- 2 inch circles with fit in a 12x16 rectangle.

Each brick has an area of 1ft x 1ft ie 1 sq foot. So you would need 308 bricks.

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.

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.

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 would depend on whether the bricks were 4 inch x 8 inch or 4 cm by 8 cm or some other units.

Let's see here.... If you layed them without mortar between them that would be 18 bricks for every 4 square feet so your answer is 648 bricks.

A single layer will require 144 bricks.

3 ft = 1 yard 12 in = 1 foot 30 yard**2 * (3**2)(12**2) = 38880 inch**2 38880 inch**2 /32 inch**2 = 1215 bricks You should buy extra just in case. If the yard is not twice as long as it is wide, you'll have to cut the bricks and you may lose some (especially if you have an irregularly shaped yard).
