I was reading the materials the school gave out during this summer and apparently they classified the great pyramids of Giza as building but the Sphinx as a sculpture. Similarly, they classified Eiffel Tower as a building but the Statue of Liberty and Mount Rushmore as sculptures.
If I seal every tomb chamber from every pyramid, would that make them non-buildings? If I build free warehousing inside the statue of liberty, would that make it a building?
The Eiffel Tower is unusable as a building except a few decks below and a nearly-inaccessible-unless-with-great-sums-of-money apartment at the top with no one living in it usually as of now. How much of a building really is it?
