A prism, by definition, is 3D. You cannot have a 2D prism.
it a triangle as a 2d shape
no, it's 2d
A pentagonal prism has 7 faces - a prism of any 2D object will have (2D sides + 2) faces.e.g. An octagonal prism - 8 side octagon, 8+2=10 face prism.
No. A rectangle is a 2D shape, while a prism is a 3D figure.
Every prism has a 2D face. If it does not, it cannot be a prism.

A prism is 3d and a pyramid is in 2d
A pentagonal prism has 7 faces - a prism of any 2D object will have (2D sides + 2) faces.e.g. An octagonal prism - 8 side octagon, 8+2=10 face prism.
You cannot have a 2d prism. The 2d cross section will depend on the plane of the cross section.
No. A rectangle is a 2D shape, while a prism is a 3D figure.
The latter
because triangle is only 2d shape but a prism is 3d shape
It is simply called a pentagonal prism. That is a prism based on the 2D shape known as a pentagon.
No, it is a 3D shape.
