What is the difference between a prism and a pyramid?
A prism: a solid with 2 bases (congruent and parallel polygons) connected by multiple parallelograms (lateral faces).
A pyramid: a solid with only one base (a polygon) that connects multiple triangles (lateral faces).
What is Euler's Formula?
F (faces) + V (vertices) - 2 = E (edges)
