A 3D diamond, often represented as a regular octahedron, has 12 edges. In geometric terms, a diamond shape can also refer to a rhombus in 2D, but in 3D, the octahedron is the closest representation of a diamond-like form. Each vertex of the octahedron connects to four others, contributing to the total edge count.
As a 2d object, a diamond had four sides. As a 3d object, there are many different types of diamonds, all with their own numbers of vertices, edges and faces.
6 edges.
it is a 3D shape with 8 faces 8 edges and 6 vertices if you want a picture of it type in pcures of 3D diamonds.
No corners and two edges !
A pentagonal prism will have 15 edges.
I believe it would have nine edges.
