Some 3D solids have faces, edges and vertices.
A prism is a 3D solid with a uniform cross-section. The two end faces of a prism are identical in shape and size. If you make a cut parallel to the ends, the cross-section exposed will be the same shape and size as the ends.
A pyramid has a polygon as its base and the rest of its faces are triangles that meet at the same vertex.
Here are some common 3D solids.
|Cube||6 (all squares)||12||8|
|Cuboid||6 (all rectangles)||12||8|
Some 3D solids, such as the cone and the cylinder, have faces and curved surfaces.
Some 3D solids, like the sphere, just have a curved surface.
