An octagonal prism
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.
The three-dimensional shape that has 2 octagons and 8 rectangles is called a truncated octagonal prism. A truncated octagonal prism is a polyhedron with 10 faces, including 2 octagonal faces and 8 rectangular faces. The octagonal faces are the bases of the prism, while the rectangular faces are the lateral faces that connect the bases.

There is no such shape.
A three-dimensional octagon is commonly referred to as an "octagonal prism." This geometric shape consists of two parallel octagonal bases connected by rectangular faces. The octagonal prism retains the properties of an octagon while extending into the third dimension.
