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
[edit]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]
