<human>:  Would it be possible to fit a football field in Alcatraz Island?
<bot>: Yes, Alcatraz Island is large enough to fit a football field. Alcatraz is 511 meters by 180 meters, which is large enough to fit a football field. A football field is 91 meters by 48 meters, which is smaller than Alcatraz, but still large enough to fit a football field.
