3D shapes

This week we have been investigating 3D shapes.  

We have tested Euler's formula of 
Faces + Vertices - Edges = 2 
and found it worked!

The formula is written as:   F+V-E = 2

We then made some polyhedra (polyhedrons) of our own.  These are 3D shapes that have only straight edges and flat faces.

We then checked that Euler's formula worked for our polyhedra.  You'll be pleased to hear it did!
