ok... how many faces of a square based pyramid..?

anonymous · Answer

5

campbell_st · Answer

how many edges and vertices

anonymous · Answer

8 edges.
and 5 vertices

campbell_st · Answer

so the square base has 4 vertices and 4 edges... and 1 vertex to form the pyramid and you double the number of edges. 


Also for polyhedra there is Eulers Formula

Faces + vertices = edges + 2

  5     + 5          =  8 + 2

Is that for the part where they ask to describe the relationship?
