11 x 15 mail bags

A classic problem!

To calculate the total number of items in 11 x 15 mail bags, we need to multiply the number of bags by the number of items in each bag.

Let's assume each mail bag can hold 15 items (this is a common assumption, but it may vary depending on the type of mail and the size of the bags).

So, the total number of items would be:

11 bags x 15 items per bag = 165 items

Therefore, there are 165 items in 11 x 15 mail bags.
