It depends greatly. If you do all bone out cuts vs bone in cuts it will be a very different answer. If you're doing ribs, bone in shanks, etc, it's going to be a bunch.
AK says a 1600 lb moose yields 500 lbs boned out. A cubic foot of meat weighs about 45 pounds but you don't have perfect usage of space.
If you had all boned out meat, stacked it neatly and didn't need to see or sort through it you could probably fit it in 12-15 for the larger bulls but I've never done it, just enjoy math problems.
It's usually less than you think, when you get those nice white bricks, they don't take up much space.
