None, but you can cut a cube into any number ≥ 2 of triangular prisms.
Triangular Prisms don't have any vertical edges
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.

14 if the triangular cross section has a right triangle, 12 otherwise.
None normally
i be leave there are 5 edges on a triangular prism

Zero!
A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.
A triangular prism has three rectangular faces which, between them, will have 4*3 = 12 right angles. It also has two triangular faces and these can have another 2 right angles. So the answer is 12 or 14, depending on whether the triangles are right angled or not.
Triangular Prisms don't have any vertical edges
This is because there is no limit on rectangualar prisms and most boxes can hold cube or rectangular prisms not triangular pyrimids or prisms or hexagonal prisms.
A triangular prism has a total of nine angles. Each of the two triangular faces has three angles, totaling six angles. The three rectangular faces each have one right angle, adding three more angles. So, the total number of angles in a triangular prism is 6 + 3 = 9 angles.
