Well, one system says if a grain of sand is bigger than 2mm, it's a pebble, and a pebble bigger than 100 mm is a cobble, and a cobble bigger than 256 mm is a boulder, so you could use "pebble" for "gravel" I reckon.

It depends how deep you want the gravel to cover, if you want it to be 2 inches deep it's going to cost more than 5 inches. Also it depends how big the gravel is cut, I think that the smaller the gravel is the more it costs.
