A triangular prism, where the two ends are triangles.
That shape is called a triangular prism. A prism is made of rectangles arranged in a tube with any 2D shape at the ends. This shape determines what kind of prism it is, you can get pentagonal, hexagonal, and many other types of prism.
A shape with 5 sides is a pentagon.However, the term face is only applied to three-dimensional forms,and a shape (solid) with 5 faces is a pentahedron.There are no regular pentahedrons. The two forms are the square pyramid and the triangular prism. The former has 4 triangular sides and a square or rectangular base; the latter has 3 rectangular (or square) faces and two triangular ends.
It looks like a pup tent.The two parallel ends of the shape are triangles and the faces that connect these are parallelograms, usually rectangles.
No, they are not There are many 3D shapes which are neither prisms nor pyramids. A prism has flat, rectangular faces along its length and two ends, which can be triangular, square, hexagonal. An exception is the circular prism which is normally called a cylinder. A pyramid may have any shape for its base, However if the base has 5 sides then the prism will be formed from 5 triangles rising from its base. A special case is the pyramid which has a circular base. We usually call it a cone. Poly means many and hedron means sides, so a polyhedron is a 3D shape with many {usually flat) sides, which are more accurately called "faces" in mathematics. Hence an octahedron has eight faces. Imagine a pyramid (like the Egyption ones) with 4 triangular faces in the air and standing upon a fifth one (its base on the sand). If you made two of such pyramids out of card and glued their square bases together, the remaining shape that we see is an octahedron. (Imagine that the glued bases are not there any more).

An 8-faced 3D shape is called an octahedron. It is a polyhedron with eight triangular faces, 12 edges, and six vertices.
triangular prism
A prism whose ends are 18-gons.
A triangular prism, where the two ends are triangles.
A PRISM is a solid whose side faces are parallelograms and whose ends(or bases ) are congruent parallel rectilinear figures.
It ends up with 88 edges
A prism whose ends are polygons with n sides will have 2n + 2 faces in all.
That shape is called a triangular prism. A prism is made of rectangles arranged in a tube with any 2D shape at the ends. This shape determines what kind of prism it is, you can get pentagonal, hexagonal, and many other types of prism.
A rather simplistic answer is: A cube or cuboid shape has (usually) 2 sides, 2 ends, 1 top and 1 bottom.
A square prism is one whose two ends are square and the remaining 4 faces are rectangles.
