2  A prism is a shape that can lay on this side long ways or up ways that doesn't have a apex.  Every prism has straight long face.  A polygon is a 2-d shape that forms a prism.

3  A pyramid has a apex that is a the top of the pyramid.  The pyramid has a polygon as a bottom.  The pyramids are named by their base.

4  The shapes that form the different types of prisms and pyramids are eighther 2 shapes or 1 shape.  The also have a form all different.  These prisms and pyramids are 3d shapes.

5  A pentagonal prism has a pentagon on a face or side of the pentagonal prism.  That forms into a pentagon.  If you cut a pentagon in paper it’s a pentagonal prism.  A pentagonal prism has 15 edges, 10 vertices and 7 faces.

6  A hexagonal prism is made out of two shapes.  1. a rectangle witch makes the sides, you need 6.  2. a hexagon witch is for the base and top, you need 2.  The hexagonal prism has 8 faces, 18 edges and 12 vertices.

7  A rectangular based pyramid has 2 shapes a rectangle and a triangle.  1. a rectangle has 4 edges, 4 vertices and 2 faces.  2. a triangle has 3 edges, 3 vertices and 2 faces.  If you put them together you get a rectangular based pyramid that has 8 edges, 5 vertices and 5 faces.

8  A square based pyramid is formed by the square underneath the for triangles that are connected to the square underneath.  A square based pyramid has 7 edges, 5 vertices and 5 faces.
