It depends on the size of the bricks and their orientation when they are laid.
Assuming it's 4x8 inches, then one brick = 1/3 feet * 2/3 feet, so the area of a brick is 2feet2/9. 120 feet2/(2feet2/9) = 540 bricks
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.

120 bricks/m²
Considering the area is rectangular and each side is able to contain an integer number of each side, we have 240/(2/3 * 1/3) = 120(9) = 1080 bricks.
80 ft x 120 ft = 9600 ft2 of concrete
120 mm = 0.39 feet.120 mm = 0.39 feet.120 mm = 0.39 feet.120 mm = 0.39 feet.

120 kilometers = 393,700.787 feet
120 feet = about 36.6 meters.
