3D shapes have faces, edges and vertices.
A prism is a 3D shape with a uniform cross-section. This means that you would see the same shape no matter where you cut through the shape (parallel to the ends). The two end faces of a prism are the same shapes, and the other faces are rectangles.
A pyramid has a polygon as its base and the rest of its faces are triangles that meet at the same vertex.
Here are the most common 3D shapes.
|Cube||6 (all squares)||12||8|
|Cuboid||6 (all rectangles)||12||8|
