Quikrete's 50 lb all-purpose gravel bag holds about 0.5 cubic feet, so 54 of them make one cubic yard.
HomeGuide lists 40 lb bags of topsoil at $2 to $6 each. HomeGuide puts topsoil at $10 to $50 per cubic yard. Compare the two once you know how many bags you need; past a few dozen bags, bulk is usually the cheaper way to buy.
Weight to carry
Every cubic foot of topsoil weighs about 80 lb. Check your vehicle's payload before you load a trip's worth of bags.
