Sides and faces are the same thing, and an octahedron has eight.
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.
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.
Three pairs.
The same as a right cylinder: 3.
13 vertices. A pyramid always has the same number of faces and vertices.
6 faces, 8 vertices, and 8 edges(edges and vertices are the same).
The same as a cube or cuboid. 6 faces, 8 vertices and 12 edges.
pentagon
A crystal is a polyhedral shape. The number of faces (which means the same thing as sides) depends on the crystal.
