If a university football stadium has a total capacity of 81,500 seats and is at full capacity, it means that every single seat in the stadium is filled with spectators. This would represent the maximum attendance for a game held at that stadium.
In terms of implications, having a full-capacity crowd could lead to significant revenue from ticket sales, concessions, and merchandise. Additionally, a full stadium often contributes to a lively atmosphere, which can enhance the experience for both players and fans.
