If e=v+2-r where e = 17, r = 6
then 17 = v + 2 - 6 or v = 21.
If you are a solid figure with no vertices or edges, then you are a Sphere.From the lighter side: And that means that we can no longer be friends...
A square based pyramid has 5 vertices, 8 edges and 5 faces.
cube
6
It the cylinder because it has 2 bases 2 faces 0 vertices And 0 edges
It is a triangular prism that has 5 faces, 9 edges and 6 vertices
The solid figure that has the same number of faces and vertices and has 8 edges is a cube. A cube has 6 faces, 8 vertices, and 12 edges, so it fits the description given.
sphere
A hemisphere
Vertices are points in a solid, or 3-D figure, where edges meet.
...CUBE hAS 6 CONGRuent faceS ,8 vertices and 12 EDGES
A rectangle is a plane figure and so has only one face. It has four sides (edges) and four vertices.
