hexagonal prism
In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has 8 faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces.

The Shape That Has 8 Sides Is A Octagon Which Has 8 Equal Sides
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 shape with eight straight sides is called on octagon. There is not another specific name, but you could call it the more generic name: polygon.
