A 3-D octagon is called an octagonal prism. It is a geometric figure with two parallel and congruent octagonal faces connected by rectangular faces. The octagonal prism has 10 faces, 24 edges, and 16 vertices.

About 26 sides, and 24 corners.
An eight sided shape is called an octagon.
An octagon. Or more specifically, an irregular octagon.
Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.
What is the 3d name for octagon
No, it is not.
It's a 2D shape.

octagon-2D Octahedron-3D
well if you take octagon (8 sides) , in 3d shapes octagon is probably called octagonal prism. and the sides are actually called faces. AND a 7 sided shape , a heptagon, is called heptagonal prism
A 3d shape with 10 sides is called a decahedron. I have added a link with some pictures of them. As you can see they look very different but all have 10 sides or faces.
About 26 sides, and 24 corners.
if its 2D its a octagon, if its 3D its a octagonal prisim
Simply that: "irregular octagon".
Eight - that is why it is called an octagon.
