Geometry
A triangular prism is a special case of a prism where the base is a triangle.
Equations
- Variables:
l ⇒ length of edges of triangular prism
- All points (x, y, z) that lie on the surface of a triangular prism will satisfy the following equations:
Unknown
- All points (x, y, z) that lie on the edges of a triangular prism will satisfy the following equations:
Unknown
- The hypervolumes of a triangular prism are given by:
total edge length = 9l
surface area = l2(3 + 2-1√3)
volume = l34-1√3
- The planar cross-sections (n) of a triangular prism are:
