A Pentagonal Pyramid would have 10 edges.
5 edges along the bottom/the base of the pyramid and then 5 edges extending to the tip of the pyramid from the base.
Hope that helps.

Sphere, cylinder and a cone
no, it is sphere is not a perfect circle. because sphere is 3dimensional figure and circle is 2 dimensional figure
A cube has 6 faces. The number of faces, alone, is not sufficient to figure out the number of edges. For example, a cube has 12 edges. A pentagonal pyramid also has 6 faces, but it has 10 edges.
There can be no such shape.
There is no 3 dimensional figure with JUST 3 edges.

It is a pentagonal prism
There can be no such shape.
A hexagonal figure have 6 edges
There is no 3 dimensional figure with JUST 3 edges.
An octahedron has 12 edges.
There is no solid figure with only four edges. The smallest solid figure is the tetrahedron, made up of four triangular faces, but it has six edges.
You have to count the lines on a solid figure
If the figure has curved edges, then it's not a "rectangle".
