Apples and Oranges. Without knowing how thick the 450 sq. ft. area is or how thick you want it to be you can't convert to cubic yards. A cubic yard has 27 cubic feet. One square foot 3 inches thick would be 1/4 cubic feet. 4 sq. ft. 3 inches thick would be 1 cubic foot.
450 sq. ft. 3 inches thick is 112 1/2 cubic feet or just a bit over 4 cubic yards.
450 sq. ft. 4 inches thick is 150 cubic feet or 5 1/2 cubic yards.
The volume of the hole is (782 x 1.5) = 1,173 cubic ft. 1 cubic yard = 27 cubic ft 1,173 cubic ft = (1,173 / 27) = 43.444 cubic yards (repeating)
(3,600 square ft) x (1 ft) = 3,600 cubic ft.1 cubic yard = 27 cubic ft3,600 cubic ft = 3,600/27 = (133 and 1/3) cubic yards
500 sq ft X 1/12 ft / 27 cubic ft./cubic yard = 1.5 cubic yards
4.938 cubic yards.
It takes 5.0926 cubic yards or 137.5 cubic feet.

To find out how many yards of concrete you need for your 450 sq ft patio, you would first need to determine the thickness of the concrete you plan to pour. Let's assume a standard 4-inch thickness. One cubic yard of concrete would cover 81 square feet at a 4-inch depth. So for a 450 sq ft patio at 4 inches thick, you would need approximately 5.56 cubic yards of concrete.
8.5 ft * 16 ft * 4.5 ft = 612 cubic ft = 612/(3*3*3) cubic yards = 22.666... cu yards
150 square yards 3 feet = 1 yard 450/3 = 150
450 ft = 450ft (1yd/3ft) = 150yards

1 cubic yard = 27 cubic feet 2 cubic yards = 54 cubic feet . . . 435 cubic yards = 11,745 cubic feet
(3,600 square ft) x (1 ft) = 3,600 cubic ft.1 cubic yard = 27 cubic ft3,600 cubic ft = 3,600/27 = (133 and 1/3) cubic yards
It is 1.185185... cubic yards.
Answer: 150 yd = 137.16 meters.
25 cubic yards is 675 cubic feet.
