1 cubic yard of crushed rock fills 3/depth in feet square yards.
It depends on what kind of rock it is.
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
Volume = (1,200 square feet) x (1/3 foot) = 400 cubic feet = 14.81 cubic yards
38ft*6ft*1.5inch = 38/3 yards*2yards*1.5/36yards = 1.055... cubic yards.
1 cubic yard of crushed rock fills 3/depth in feet square yards.
Not sure what 2b is but crushed concrete with 1 1/2" rock will cover about 60 square feet. 15 tons ends up being around 12 cubic yards.

I can't tell what the units of the "200 x 10" are, so I have to makeassumptions.200 feet x 10 feet . . . . . 74.1 cubic yards for each 1 foot deep200 feet x 10 inches . . . . 6.17 cubic yards for each 1 foot deep200 inches x 10 inches . . . 0.514 cubic yard for each 1 foot deep

A cubic yard of stone that is 4" thick would cover 9 square yards or 81 square feet. If you need to cover 7000 sq. ft., you would need roughly 86.5 cubic yards. That's a lot of rock.
38ft*6ft*1.5inch = 38/3 yards*2yards*1.5/36yards = 1.055... cubic yards.
It depends how densely it is distributed.
Unless the rock is completely flat, there is no point in measuring the rock in yards.
it covers 1/3 of a mile
This depends on how much rock you will use per square yard. Suppose you intend to use 1/100 tons (=20 lb) per square yard. Then if you have one ton of rock, it will cover 100 square yards. Similarly, if you intended to use 1/50 tons per square yard, 1 ton will cover 50 square yards. In general you want to use factor labeling: If you are using x tons per square yard, then write this as (1 square yard) / (x tons of rock) = (1/x)*(square yards/tons of rock) This is called a conversion factor. Now, if you have some quantity of rock, say y tons of rock, and you want to see how many square yards it would cover you just multiply (y tons of rock)*(1/x)*(square yards/tons of rock) = y/x (square yards*tons of rock/tons of rock) = y/x square yards since the labels just divide out.
