How many midsized cars can fit on one wing of a Boeing 747-400?

A Boeing 747-400 has a wingspan of approximately 211 feet (64.3 meters). Assuming an average midsized car is about 15 feet (4.5 meters) long, you could fit around 14 midsized cars side by side across one wing, considering some space for safety and practical arrangement. However, this is a rough estimate and actual capacity could vary based on specific measurements and arrangement.
