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.
12,500 tons
That's impossible to answer, since it entirely depends upon the type of rock. Some types of rock are much denser than others- for example, a piece of igneous rock such as granite, is much heavier than a same sized piece of sedimentary rock such as sandstone. It varies considerably.
