Antiprism uniform (Volume)

Description

In geometry, an n-sided antiprism is a polyhedron composed of two parallel copies of some particular n-sided polygon, connected by an alternating band of triangles.Antiprisms are similar to prisms except the bases are twisted relative to each other, and that the side faces are triangles, rather than quadrilaterals. A right antiprism has the two n-gonal bases and, connecting those bases, 2n isosceles triangles .A uniform antiprism has, apart from the base faces, 2n equilateral triangles as faces. The volume of a uniform prism is related to the edge-length of the antiprism and the number of the faces.
