A triangular prism.
It has two congruent plane faces which are parallel to one another. Each point on the edge of one face is connected to the corresponding point on the other face. The shape, therefore, has three or more faces.
You don't get any sides on 3D shapes. However, here are the features of both shapes: Square based pyramid: 5 faces, 5 vertices, 8 edges Triangular prism: 5 faces, 6 vertices, 9 edges. Then again, it depends on what type of base the pyramid in question has.
No, a dodecahedron is a 3-dimensional shape. Some of the 6.4 million topologically distinct dodecahedra have only triangulat faces, there are many more in which some faces, but not all, are triangular.
