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
No 3D shape with FLAT SIDES has exactly 3 faces. 4 is the minimum.
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.
-3
I'm not certain, but i believe it would be a nonadecanonahedrinnonadaca- is 19decanona- is 90hedrin- is a 3d figure
A 3d shape can have infinite sides
sides are the face of a 3d shape and verticies are the corner of the shape
square
That is a Dodecahedron.
A septadecahedron has 17 sides to it.
Pentadecagon; Pentakaidecagon
A shape with 7 sides.
2D shape = Decagon 3D shape = Decahedron
