a 10 lb can of green beans will feed 50 people with 3 oz portions.
Depends what else you are having .
I would NEVER feed guests canned beans. -Fresh are tastier, healthier and only a fraction more costly.
I would use 150 cans
it depends on how much people want!
Lennie and George share one can of beans.
Are they only eating beans or it a single veg as part of a dinner meal.How can we give a reasonable answer if you don't give us all the facts.
I would use 25 pounds of fresh green beans for 100 people
10
presumably they are having other food also. So 10 people should use 3 can of beans
One normal size can would do 2-3 people, depending on how big a portion they want.
You need about 10 twenty eight ounce cans
Required: Two tin cans, a length of string. A small hole is made in the bottom of each can large enough for the string diameter. The string is pushed through the hole in bottom of each can and a large knot tied to prevent it from pulling back through the hole. when the string is kept taught between the cans, it is possible to transmit and receive sounds from one can to the other via the taught string. The string acts as a mechanical sound conductor. Increased efficiency can be achieved by substituting suitable wire for the string. Of course if you want to cheat - just use your I-phone!
Depending on the size of the cans, a canner might be able to fit multiple cans each inside one another all together in one large can. However, a canner might be canning peas or beans or octopi, so depending on his skills and workforce, he may be able to can many cans.
