Q:

# What figure has five faces, eight edges and five vertices?

A:

A square pyramid, a pyramid with four triangular sides and one square side, is a figure with five faces, eight edges and five vertices. It is a kind of three-dimensional solid. The pyramids at Giza, Egypt are examples of such a figure.

Know More

The sides of a three-dimensional solid are called its faces. Since a square pyramid has four triangular sides connected to the perimeter of the fifth square side, this solid is said to have five faces. Edges are places where two sides of a three-dimensional solid meet. Vertices are where three sides of a dimensional solid meet and are often called corners.

The number of edges of any polyhedron can be calculated using the formula: E = V + F - 2, where "E'" denotes the number of edges, "V" indicates the number of vertices and "F" represents the number of faces. It is derived from the famous polyhedral equation formulated by Leonhard Euler, which states that V + F - E = 2.

A vertex is a corner on a polygon, polytope or polyhedron, and when faces, facets or edges of an object come together, a vertex forms; however, because a sphere features no meeting points, it has no vertices. Even though a sphere does have one continuous surface, its lack of meeting points with any other surface means that it technically has no faces. Spheres have no lines, so they also have no edges.
