Across
  1. 5. a square prism. The length of the prism is the same as the width. It has 6 faces, 8 vertices and 12 edges
  2. 7. has 8 faces. Each face is an equilateral triangle. Four triangles meet at each vertex. It has 6 vertices and 12 edges
  3. 8. has faces that are the same regular polygons
  4. 11. a polyhedron with the same cross-section all along its length
  5. 12. has 12 faces. Each face is a regular pentagon. Three pentagons meet at each vertex. It has 20 vertices and 30 edges
  6. 14. line segment where two faces of a polyhedron meet
  7. 15. polygon that makes up a three-dimensional shape
Down
  1. 1. has a rectangle at both end faces. Each other face is a rectangle. It has 6 faces, 8 vertices and 12 edges.
  2. 2. a 3-dimensional solid with at least 4 flat faces. Each face is a polygon. The plural is polyhedra.
  3. 3. a solid figure where all the points on the surface are the same distance from the center
  4. 4. has 4 faces. Each face is an equilateral triangle. Three triangles meet at each vertex. It has 6 edges and 4 vertices.
  5. 5. a circular prism. It has circles as the end faces and the length is a rectangle if you unwrap it
  6. 6. polygon that makes up a three-dimensional shape
  7. 9. a poylgon base and an apex
  8. 10. the amount inside a 3-dimensional shape. The label is cubic units or units3
  9. 13. a circular pyramid. It has a circle base and an apex. It has 1 vertex
