Sides and faces are the same thing, and an octahedron has eight.
The faces of a cube are all the same shape - a square.
They do it for shock value. Same reason that they sometimes have blood on their faces.
Bases and faces are the same, so a triangular prism will have 6 faces/bases.
5 faces. It is the same for a triangular and square pyramid too.
Sides and faces are the same thing. A hexagonal prism has 8 faces and 12 vertices.

5 faces and 5 vertices. Since sides are the same thing as faces, there are 5 sides.
The same as a right cylinder: 3.
Same as on a cube: six.
Three pairs.
13 vertices. A pyramid always has the same number of faces and vertices.
