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...

36 tiles. I would hire a tiler if I was you, this doesn't sound like your 'thing'

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...

196

115 should do it!

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.

1,350 of them.

488 bricks.

450 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.

A 12x12 inch paver is one square foot. So you would need 240 square feet.
