The "math" can be quite complex, because estimates range anywhere from 1/4 acre to feed a family of four to 1 acre to feed 1 person. It depends on how intensely the land is managed, climate zone, caloric requirements, etc. I pack my veggies in much closer rows than you're supposed to, but they do fine.
It's funny, I built one 12"x48" window box just for herbs and I barely use them! I have oregano, thyme, thai basil, mint, lavender, bee balm, parsely, cilantro, even green onions, and I kind of forget they're there. A shaker of dried herbs provence works for me most of the time.
