How many loaves of banana bread for 200 people?

The amount of banana bread needed for 200 people depends on the size of the loaves and how much each person eats. Generally speaking, a loaf of banana bread can be sliced into around 10-12 pieces. If you assume each person will eat 1 slice, you would need around 17-20 loaves of banana bread to serve 200 people. However, if you expect some people may want to eat more than one slice, it would be better to make a few extra loaves just to be safe.
