A yard is 3 feet so 3 feet cubed would be 27 cubic feet in a cubic yard
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.
231 cubic inches = 1 gallon1 cubic foot = 1,728 cubic inches = 7.48052 gallons (rounded)Volume = 15' x 10' x 3' = 450 cubic feet = 777,600 cubic inches = 3,366.234 gallons (rounded)
450 liters = 118.877 gallons or 15,216.3 oz

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.
56.25 gallons
There are 3 feet in one yard. Therefore, 450 feet is equal to 450/3 = 150 yards.
(250 + 450) * 9 / 43,560 = 23 acres
It would use 9 gallons in 450 miles.
