How many faces, vertices, and edges does a square-based pyramid have?

A square-based pyramid is a three-dimensional geometric shape that comprises a square base and four triangular faces that meet at a common vertex. To determine the number of faces, vertices, and edges it has, let’s examine its properties:

Faces:

A square-based pyramid has a total of 5 faces. The square base accounts for one face, and the four triangular faces make up the remaining four faces.

Vertices:

A square-based pyramid has 5 vertices. These vertices occur at each of the four vertices of the base square and the apex of the pyramid where all the triangular faces meet.

Edges:

A square-based pyramid has 8 edges. Each of the four edges of the square base connects to the apex of the pyramid, and the remaining four edges connect the apex to the midpoint of each of the four edges of the square base.

Therefore, a square-based pyramid has 5 faces, 5 vertices, and 8 edges.
