5 vertexes, 4 faces, and 8 edges
if you can find the vertexes which is just THE POINTS and if you can find how many faces it has you can find out how many edges is on the 3D object this is a short cut add the vertexes and the faces together then subtract that by two Example: a cube has 5 faces and 5 vertex's add it together which is 10 then subtract 2 and a cube has 8 edges * * * * * The first part is true, the second - the example - as total rubbish. A cube has 6 faces and 8 vertices. Add together which is 14. Then subtract 2 which gives 12 edges.
A square based pyramid has five edges and five faces.

An icosahedron has 20 faces, 30 edges, and 12 vertexes. 5 polygons meet at each vertex and each face has 3 vertexes (therefore made of triangles). A dodecahedron has 12 faces, 30 edges, and 20 vertexes. 3 polygons meet at each vertex and each face has 5 vertexes (therefore made of pentagons).
The tetrahedron, consisting of four regular triangles.
A square based pyramid has 5 vertices, 5 faces and 8 edges
A square based pyramid has five edges and five faces.
5 faces 8 edges 5 corners (vertexes) * * * * * Wrong! The answer given above is for a SQUARE based pyramid. A triangle based pyramid, or a tetrahedron, has 4 faces, 6 edges and 4 corners (vertices).
