Brick is 3" x 8" = 1/4' x 2/3' = 2/12 = 1/6 square feet To fill 75 square feet you will need (75)/(1/6) = 75 x 6 = 450
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...
About 14 bricks should do it.
The surface area of a brick is therefore 16 * 16 = 256 square inches which is 256 / (12 * 12) = 1 7/9 square feet. So you will need exactly 196 / 1 7/9 = 110.25. Best make it at least 111 then.
You need the dimensions of the bricks.
115 should do it!

To find out how many 4 x 8 bricks are needed for 216 square feet, first calculate the area of one brick. A 4 x 8 brick has an area of 32 square inches (4 inches x 8 inches). Converting square feet to square inches, 216 square feet equals 31,104 square inches (216 x 144). Dividing the total area by the area of one brick, 31,104 ÷ 32 equals 972. Therefore, you would need 972 bricks to cover 216 square feet.
2700 4" x 8" bricks (plus 10% waste)
To determine how many 4 x 8 bricks are needed for 160 square feet, first calculate the area of one brick. A 4 x 8 brick has an area of 0.33 square feet (4 inches = 1/3 foot, 8 inches = 2/3 foot; 1/3 x 2/3 = 0.22 square feet). Next, divide the total area (160 square feet) by the area of one brick (0.22 square feet), which results in approximately 727 bricks needed.
