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.
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
