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.
