There are 2pentagonal faces with 5 vertices, giving 10. Nonuniform pentagonal prisms called pentaprisms are also used in optics to rotate an image through a right angle without changing its chirality. Additionally, all pentagonal prisms have fifteen edges. A pentagonal prism is basically two penatgons joined by sides by squares.
It can be seen as a truncated pentagonal hosohedron, represented by Schläfli symbol t Use If faces are all regular, the pentagonal prism is a semiregular polyhedron, more generally, a uniform polyhedron, and the third in an infinite set of prisms formed by square sides and two regular polygon caps. In this lesson, we find a general formula for the surface area of a pentagonal prism. 1 As a semiregular (or uniform) polyhedronĪs a semiregular (or uniform) polyhedron The pentagonal prism is made of two pentagonal bases and five rectangular sides. A prism is a solid object with the same ends and with flat sides.
