A pentagonal prism is a three-dimensional geometric shape with two parallel pentagonal bases connected by five rectangular faces. The pentagons are identical and lie in parallel planes, while the rectangular faces connect corresponding sides of the pentagons. This shape is classified as a type of polyhedron. The properties of a pentagonal prism include having 7 faces, 15 edges, and 10 vertices. The angles and dimensions of the pentagonal bases determine the overall size and proportions of the prism. Pentagonal prisms can be found in various applications, including architecture and design, where their unique shape adds visual interest.
