In places like a desert a lot of times they aren't, because they don't have a lot of rain and they don't really get snow, but in places like Michigan, our roofs might collapse with the weight of all the snow we get in the winter so make them in the shape of a triangular prism so the snow wont really stay on the roof, but there are still some people who make their roofs flat for whatever reason.
A triangular prism can have a square or triangular base.
You can call it a "triangular prism" rather than "triangular based prism" ... saying a prism is "triangular" imply that the base is a triangle. There's no other name that I know of. A prism is just a 3d shape, so all you have to say is <type of shape> + prism to get the point across.

A triangular prism has triangular bases, a heagonal prism has ... you guessed it! ... hexagonal bases.
A triangular prism (like a bar of toblerone).A triangular prism.
You can have a triangular prism but not a triangular cuboid which is a rectangular shape.
A cuboid prism has no triangular faces
A rectangular prism is a cuboid which has 8 vertices (corners), while a triangular prism has six verticesA triangular prism is like a cylinder but with triangles instead of circlesA rectangular prism is the same
It is a triangular prism.

A triangular prism has a triangle and a rectangular prism doesn't.
A triangular prism has two triangular faces, a rectangular prism does not have any.
A triangular prism.
There are an infinite number of shapes. A tetrahedron (triangular pyramid), a square-based pyramid, a pentagonal pyramid, a hexagonal pyramid, etc. A triangular prism, a rectangular prism (cuboid), a pentagonal prism, etc are some examples.
No, that will not give you the volume of a prism (since it's a triangular shape, not cuboid). For volume of a prism, you need to find the area of one of the end triangles, then multiply by the length of the prism.
