Solve:
Count the number of faces
- One on the bottom
- Four connecting to each side of the square at the bottom
1 + 4 =
Count the number of edges
- Four on the bottom that shape the square
- Four on the sides that shape the triangles
4 + 4 =
Count the number of vertices
- Four on the bottom that surrounds the square
- One on the top where triangles intersect
4 + 1 =
