# How many 12x12 inch bricks would you need to lay for a 396 foot patio?

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:

to compensate for cutting, breakage, etc.

### How many 16x16 inch bricks would you need for a 144 foot patio?

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.

### How many 16 inch bricks needed for a 256 square foot patio?

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".

### How many bricks would you need if the area of a patio is 100 square feet and one brick is 3x 4''x 9''?

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.

###### Asked in Math and Arithmetic

### The patio is 15 feet by 8 feet the bricks are 24 x 24 how many do you need?

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.
