Faces: 6 Faces: 5
Vertices: 8 Vertices: 6
6 + 8 - 2 = 12 5 + 6 - 2 = 11
Edges: 12 Edges: 11
For Maths Time we had to make polyhedron shapes with maths counting sticks and glue tack. A polyhedron shape is any shape that is solid and has many faces, it would normally have 6 or more faces. We also learnt a formula that we could use to find out the amount of edges a shape has. The formula is F + V - 2= E. The "F" represents the faces, the "V" represents the vertices and the "E" would represent the edges. For example we could use a cube. A cube has 6 faces and 8 vertices so 6 + 8 - 2 = 12. So that means a cube has 12 edges. I found this really interesting that we could use a simple sentence to figure out the amount of edges a shape has.
