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.).
The author marked this model as their own original creation.
