Right Pentagonal Prism

A right pentagonal prism is a prism with two parallel and congruent pentagonal faces and five rectangular faces perpendicular to the triangular ones. This is a polyhedron with 10 vertices, 15 edges, and 7 faces. If the pentagonal faces are regular, the prism is also called regular, in which case the rectangular faces are all congruent.

The rectangular faces are said to be lateral, while the pentagonal faces are bases. If the bases are horizontal, they are sometimes called the top and the bottom (faces). The sides of the lateral faces are also called lateral edges.

You can check the Euler's formula for this solid: 10 - 15 + 7 = 2.

What if applet does not run?

Drag the mouse to rotate the prism. Use the right button to remove and put back individual faces.
