That would be some kind of prism. To answer the question more specifically, I would need to know the shape of the bases.
A prism..
When a base is congruent it is the same shape and size, and parallel is when they will never touch. Therefore, on a square the top and bottom are congruent parallel bases. Some other examples are: Cylinders, rectangular prisms, and of course parallelograms.
A rectangular pyramid has 5 faces: a rectangular base, and 4 triangular faces.

A prism. A triangular prism has two congruent triangles as bases, rectangular prism, pentagonal prism, etc.
Prism!
a rectangular prism yeah
A triangular prism. :)
No.
A prism has two parallel and congruent bases in the shape of polygons. Example - a cereal box (is rectangular prism). The top and bottom are rectangles(a polygon). They are the same size and shape (congruent) and also parallel. A cube (think of six sided dice) is a special rectangular prism. Imagine a a box where the top and bottom are triangles (of the shape size and shape). This is called a triangular prism.
A stop sign with thickness.
Triangular prisim. The three faces are rectangles, while the two bases are triangles.
It is a prism. More specifically, "A solid figure that has two bases that are parallel, congruent polygons and with all other faces that are parallelograms." This describes the general prism. Replace "polygons" with "triangles" and you have specified a triangular prism.
Look at the prism. If all faces are rectangular (or square) then so are the bases. Otherwise they are the two congruent parallel faces that are not rectangular. Look at the prism.

A triangular prism (Two triangles as the two bases)
They are prisms. The bases may be any polygons with three or more sides.
