Yes.
All the faces of a triangular prism must be flat. So finding them should not be too difficult!
A prism has no curved surfaces. It has 5 or more flat faces.
The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.
Faces
6
There are five of them.
A triangular-based prism has five flat faces: two triangular faces at the top and bottom, and three rectangular faces connecting the corresponding sides of the triangles. The triangular faces are parallel to each other, while the rectangular faces form the sides of the prism.
Two flat faces (one at either end of the prism), and a curved side.
It has 6 faces which are its flat surfaces.
A triangular prism has two triangular faces and three rectangular ones.
flat surfaces on any polyhedron are called faces
A pentagonal prism has 2 pentagonal bases and 5 rectangular lateral faces. The rectangular faces are the only curved surfaces in this context, as the term "curved faces" typically refers to surfaces that are not flat. Therefore, a pentagonal prism has 0 curved faces, as all its faces are flat.
