An 80 lb (36.3 kg) bag yields approximately
0.60 cu ft (17 L).
Divide .60 cu ft into the 27 cu ft for the hole. 45 bags. Lots of hand mixing, go with the concrete truck.
Check out the spec/data sheets.
Hope it helps.

according to your measurements it will take exactly .78 cubic yds
in converting to cubic feet 1 cubic yard = 27 cubic feet .you need approximately 80% of that which is about 22 cubic ft .check the 80lb bags label for its yield usually a 1/2 cubic foot if thats the case you'll need about 44 bags (alot of hand mixing). Check with your local ready mix company it might be better to just have 1yd delivered ready to go . I'm partial to this idea since i drive a ready mix truck for a living.

it depends on what you're trying to do with the 3x3x3 concrete. Maybe 12 bags and some gravel mix.

3 by 3 by 3 is one yard, see how many bags per yard and youve got it

The weight of the bag doesn't matter, it's the volume of the mix.

FOUR BAGS. THIS SHOULD GIVE YOU A LITTLE EXTRA, ITS BETTER TO HAVE MORE THAN LESS.
