How many footballs would it take to fill the new Wembley Stadium?

To estimate how many footballs would fill Wembley Stadium, we need to consider the stadium's volume and the volume of a standard football. Wembley Stadium has a capacity of about 90,000 spectators and a rough volume of approximately 1.2 million cubic meters. A standard football has a volume of about 0.0042 cubic meters. Therefore, it would take roughly 285 million footballs to fill Wembley Stadium.
