In geometry, the dodecagonal prism is the tenth in an infinite set of prisms, formed by square sides and two regular dodecagon caps.

If faces are all regular, it is a uniform polyhedron.

## Use

It is used in the construction of two prismatic uniform honeycombs:

 Omnitruncated triangular-hexagonal prismatic honeycomb Truncated hexagonal prismatic honeycomb

The new British one pound (£1) coin, which entered circulation in March 2017, is shaped like a dodecagonal prism.[1]
