A pentagonal pyramid is a 3-dimensional geometric shape with a pentagonal base and five triangular faces that meet at a common point at the top. It is a type of pyramid that is commonly used in mathematics, physics, and architecture. The surface area of a pentagonal pyramid can be calculated by finding the area of the base and adding it to the area of the five triangular faces.

Pentagonal pyramids are not commonly found in everyday objects, but they do have applications in architecture and design. The famous Louvre Pyramid in Paris is an example of a pentagonal pyramid, designed by architect I.M. Pei. This pyramid serves as the main entrance to the Louvre Museum, and its shape has become an iconic symbol of the museum. Pentagonal pyramids are also used in construction, such as in the design of buildings with unique architectural features or in the creation of sculptural forms. Additionally, pentagonal pyramids are used in 3D modeling and computer graphics to create complex shapes and objects.

The formula for determining the surface area of a pentagonal pyramid is defined as:
