They are the lateral faces.
Lateral Face - In a prism, the faces that are not bases. In a pyramid, faces that intersect at the vertex.
A prism has a variety of bases but the sides are always parallelograms. A triangular prism has a triangle as the two bases and parallelograms as lateral sides. A pyramid has a variety of bases but the sides are triangles.
An octagonal prism is a solid which has 8 faces with each face having 8 sides, and 2 Bases.
no maybe 10 Face's only 1 base!
The two bases are usually perpendicular to the lateral faces.
A polygon. A prism has two identical bases or end-faces and these can be polygons with any number of sides.
It depends on what kind of prism you mean. For example, a rectangular prism has 6 bases and a triangular prism has 5 bases. A triangular prism only has two bases.
a triangular prism has to triangular bases while a rectangular prism has a rectangle as the bases.
A right triangular prism has two identical faces. Two faces may or may not be identical in an oblique prism, in which the lateral edges are not perpendicular to the bases.
Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.
Every prism has a 2D face. If it does not, it cannot be a prism.
A triangular prism has 2 bases on it!
