Bags per cubic yard

Bags = cubic feet needed ÷ cubic feet per bag, rounded up.

Quikrete's 50 lb all-purpose gravel bag holds about 0.5 cubic feet, so 54 of them make one cubic yard.

Every cubic foot of decomposed granite weighs about 104 lb. Check your vehicle's payload before you load a trip's worth of bags.

How many 0.5 cu ft bags of decomposed granite make a yard?

54 bags, because a cubic yard is 27 cubic feet.

How many bags of decomposed granite cover 100 sq ft?

At 3 inches deep you need 25.0 cubic feet, which is 50 bags of 0.5 cu ft or 13 bags of 2 cu ft.
