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.
To calculate how many 16-inch by 16-inch bricks are needed for a 12 ft. x 16 ft. patio, first convert the patio dimensions to inches: 12 ft. = 144 inches and 16 ft. = 192 inches. The area of the patio is 144 inches × 192 inches = 27,648 square inches. Each brick has an area of 16 inches × 16 inches = 256 square inches. Finally, divide the patio area by the brick area: 27,648 ÷ 256 = 108 bricks needed.
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.
432 x 12 inch x 12 inch bricks for an area 18 feet x 24 feet
19 1/2 tiles plus you want to add 10% for waste
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.
