How wide is a stack of 5 dollar bills?

A stack of five-dollar bills, assuming each bill is about 0.0043 inches thick, would be approximately 0.0215 inches wide for five bills stacked together. However, if you're referring to a standard stack (like a full pack of 100), it would be about 0.43 inches wide. The width can vary slightly based on the condition and age of the bills.
