The cyltrianglinder is the limiting shape of an n,3-duoprism as n approaches infinity. In other words, it is the Cartesian product of a circle and a triangle. It is bounded by three cylinders and a curved cell formed by bending a triangular prism in 4D and joining the ends. Its faces are three circles and three curved faces formed by joining the ends of a rectangle in 3D.
The net of a cyltrianglinder is a triangular prism surrounded by three cylinders.
Equations
- Variables:
r ⇒ radius of the circular faces
l ⇒ length of the edges in the triangles
- The hypervolumes of a cubinder are given by:
total edge length = 6πr
total surface area = 3πr(r + 2l)
surcell volume = πr(3rl + √3∕2 · l2)
bulk = √3∕4 · πr2 · l2
- The realmic cross-sections (n) of a cyltrianglinder are:
