Number of bags = 1/volume of gravel in each bag .
It depends on the volume of the bag and how deep you want the gravel to be.

4000PSI, 12bags, .5cum3sand 1cu.m3 gravel
That depends on the size of your bags! My bags are 25 kg (20 l) 5 inches is 120 mm I would use 2 bags of cement and 4 bags of sand and 6 bags of gravel (well I do not buy my gravel in bags but the equivalent volume). I would mix with as little water as necessary to get a pourable consistency.
you would need 23 bags OK

You would need 54 bags of 0.5 cubic feet pea gravel to equal 1 cubic yard.
It depends on the volume of the bag and how deep you want the gravel to be.
It would obviously depend on how thickly you wanted to cover the surface, and how 'tall' a single unit of pea gravel was. You would need 736 bags per foot depth.
A cubic yard is 3x3x3= 27 cubic feet so you would need 27/.5 = 54 bags
