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 semiregular polyhedron.
Use
It is used in the construction of two prismatic uniform honeycombs:
Omnitruncated triangularhexagonal 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]}
