Explaining how to count the Faces, Edges & Vertices on 3D shapes
Let's explain the terms for you so you get a better idea! Once you know the terms, it'll be much easier to count Faces, Edges and Vertices on any specific 3D shape
If you're still unsure, just have a look at the 3D diagram which contains a Cube
below and explains it more clearly.
Faces, Edges & Vertices - The Face
Let's start with the "Face
". A face is basically any surface that is flat. Take for example the top of a table or the front of a door. That's a flat surface.
Faces, Edges & Vertices - The Edge
Now let's explain the "Edge
". The edge is basically the line that connects 2 faces together with each other. You would have a face on each end and a line connecting between.Faces, Edges & Vertices - The Vertex
And finally the "Vertex
". The vertex
is the point or corner on a shape
. This is where faces and edges
come together and meet. That end becomes what you would call the vertex.

on the cube 3D shape
