What page in Harry Potter and the Deathly Hallows is Cup destroyed?

The Deathly Hallows is a continuous story and doesn't have numbered pages like a regular book. However, the Cup is destroyed in Chapter 24: The Trio the Monster and the Deathly Hallows.

While the exact page will depend on the specific edition you're reading, the action happens relatively close to the end of the book, just before Harry and Voldemort's final confrontation.
