The other four faces are all triangles. The shapes with 8 vertices are the cube and the cuboid. The cube has 6 faces all the same, but the cuboid has different faces.

The shape of a structure affects how strong it is. Rectangles, arches, and triangles are the most common shapes used to build big structures. What happens when you push the side of a rectangle?
