You would need 31, 80 pound bags to cover 1 cubic yard at 4 inches deep. If you would like the depth to be 6 inches, 45 bags would be needed.

how deep?
To many!
2.37 cubic yards of dirt is needed to fill an 8'X4' that is 24" deep garden box. If the box is filled 12 inches, the amount of soil needed is 1.19 cubic yards and that should be deep enough for most vegetables.
It depends on the volume of the bag and how deep you want the gravel to be.
There is no way to answer that without knowing how deep the concrete will be.

4.4 bags for each 1-foot deep. 2.2 bags for each 6-inches deep. Each 5-ft3 bag will cover the area to 2.72 inches deep.

The number of bags of concrete needed for setting a fence post depends on the size and depth of the hole. Typically, one bag of concrete is enough for a 4-inch diameter post hole that is 2 feet deep. For larger or deeper holes, you may need more bags of concrete. It is recommended to consult a professional or follow the instructions on the concrete packaging for specific guidance.
16 bags for every 3 inches deep
12.3 bags for every 2 inches deep. (rounded)
To convert the weight of the sand into a volume and find out how much you need you would need to know the density of the sand as the more dense it is the less sand there will be in a 50lb bag and the more bags you would then need to fill the yard
I presume the 6 mean 6 inches, so 1/2 ft. The volume of the garden is 4.5 cu ft. So you will need between 2 and 3 bags.
The volume of 36ft2 to a depth of 6" = 1/2ft is 36ft2 x 1/2ft = 18ft3. Each bag contains 5ft3 so 18/5 = 3.6 bags are needed to cover the area, so 4 bags would have to be purchased, with 2/5 bag left over.
Well, I depends on how deep you want the layer of gravel to be. But, if you just want a enough gavel to cover the space I would say about 15 to 20 bags of it. Trust me, I have done the exact same thing you are about to do. (you can get the gravel bags from Lowe's for super cheap)
