A hexagonal figure have 6 edges
There is no 3 dimensional figure with JUST 3 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.
An octahedron has 12 edges.
You have to count the lines on a solid figure
If the figure has curved edges, then it's not a "rectangle".
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...
Any figure with 8 faces is an octahedron. If it has 18 edges, it is a hexagonal prism.Any figure with 8 faces is an octahedron.

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.
a square
A hexagon.
An octagon.
