1 yard = 3 feet.
Volume = 240 x 1 = 240ft^3
Conversion Factor = 3
240ft^3/3^3 = 8.8yd^3 --> 8.8 Cubic Yards
The answer depends on how deep the coverage will be. River Rock weighs 2,800 LBS. per cubic yard - That's 1.4 tons per cubic yard. One ton = 2,000 LBS. 2,000 divided by 2,800 equals roughly 0.71. So one ton of river rock is roughly 0.71 cubic yards. 0.71 cubic yards covers roughly 230 square feet 1" deep 0.71 cubic yards covers roughly 115 square feet 2" deep 0.71 cubic yards covers roughly 77 square feet 3" deep 0.71 cubic yards covers roughly 57 square feet 4" deep 0.71 cubic yards covers roughly 38 square feet 5" deep
6 inches = 1/6 yards. So 70 sq yards * 6 inches = 70*1/6 cubic yards = 11.66... cubic yards.
123.44 cubic yards
(522,720) x (2/3 foot) = 348,480 cubic feet= [12,906 and 2/3] cubic yards
You need 82/3 [cubic] yards for every foot deep that it has to be.
One cubic yard of mulch will cover approximately 160 square feet at 2" deep, so you would need approximately two cubic yards of mulch to cover 271 square feet at 2" deep.
To convert square yards to cubic yards, you need to multiply by the depth. In this case, 440 square yards at a depth of 1 foot would be equivalent to 440 cubic yards.

1 cubic yard will cover 15 square yards at 3 inches deep.
40.1 cubic yards
Usually a cubic yard will cover 15 square yards at 3 inches deep so I would reckon on 22 cubic yards. Hold on that I've got that wrong it's 2 cubic yards .Sorry.
You cannot directly convert cubic yards to square yards because they measure different things: volume vs. area. Cubic yards measure volume, while square yards measure area. To find how many square yards cover the same area as a cubic yard of gravel, you would need to know the thickness or depth of the gravel layer.
6 inches = 1/6 yards. So 70 sq yards * 6 inches = 70*1/6 cubic yards = 11.66... cubic yards.
123.44 cubic yards
If you say 2 inches deep, I assume you really mean cubic yards, as in how much you would have to buy? If so, the answer is 7.77, so you would need about 8 yards.
1,000,000 cubic yards.
(522,720) x (2/3 foot) = 348,480 cubic feet= [12,906 and 2/3] cubic yards
