What is a 3d nonagon called?

Answer 1

3d nonagon

Answer 2

Well honey, a 3D nonagon is simply called a "nonagon" because the term "3D" is already implied by saying it's a shape. So, no need to get fancy with the terminology here. Just call it like it is and move on with your fabulous self.

Answer 3

it is no longer a nonagon as in 3d, its facets are multipied by 3.

9 facets on the Y axis

9 facets on the Z axis

9 facets on the X axis

= 18 facets in total.

Now if you talk about a 3d figure having a total of 9 facets, then its a spherical nonagon..which is a sphere who has also 9 plain facets.
