Answer:
Right Triangular Prism
A right triangular prism is a prism with two parallel and congruent triangular faces and three rectangular faces perpendicular to the triangular ones. (If the lateral faces are not perpendicular to the bases, that is a plain triangular prism.) This is a polyhedron with 6 vertices, 9 edges, and 5 faces. If the triangular faces are equilateral, the prism is regular, in which case the rectangular faces are congruent.
The rectangular faces are said to be lateral, while the triangular faces are bases. If the bases are horizontal, they are sometimes called the top and the bottom (faces). The sides of the lateral faces are also called lateral edges.
You can check the Euler's formula for this solid: 6 - 9 + 5 = 2.
