A pentagonal prism is a three-dimensional geometric shape with two parallel pentagonal bases connected by five rectangular faces. The pentagons are regular polygons, meaning all sides and angles are equal. This shape belongs to the family of prisms, which are defined by having two identical bases and rectangular sides. Pentagonal prisms can be found in various real-world applications, such as in architecture and design. They are also studied in mathematics and geometry, where they help illustrate concepts related to volume, surface area, and symmetry. Understanding pentagonal prisms can enhance knowledge of geometry and polyhedra.
