Teaching how to apply the Pythagorean Theorem to a square pyramid (also known as a regular pyramid with a square base) is a great way to integrate geometry, spatial reasoning, and algebra.

If you plan to use this model in the classroom, scale it up by 300% for better visibility. Be sure to enable supports when printing — I skipped supports, so the top came out a bit rough. For added engagement, consider coloring the model with markers to highlight key parts (like the base, height, slant height, etc.).
