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.
a 10 lb can of green beans will feed 50 people with 3 oz portions.
presumably they are having other food also. So 10 people should use 3 can of beans
You need about 10 twenty eight ounce cans
Approximately 5 cans of 16 oz beans make 4.5 liters.
To determine how many 6-10 cans of Bush's Beans are needed to feed 150 people, consider that a standard 15-ounce can typically serves about 3-4 people. Assuming an average of 4 servings per can, you would need approximately 38 cans (150 ÷ 4 = 37.5). Therefore, purchasing 39 cans should suffice to feed 150 people.
One normal size can would do 2-3 people, depending on how big a portion they want.
