Net of a Solid Figure

A triangular prism opens up to the net at the right.

A net is a flat pattern that folds into a solid figure.

The net:


 has 2 triangular bases.


 has 3 rectangular faces between the bases.


 has 6 vertices and 9 edges.

Tell which solid figure(s) can have a base like the one named.

5. equilateral triangle 6. circle 7. rectangle 8. square

Write Trueor False. If false, explain why.

9. A prism has 5 or more surfaces,
   or faces.


10. A pyramid has 3 or more surfaces,
    or faces.


11. Steve made a net from two
    trapezoids and four rectangles.
    Name the solid figure for the
    net he made.

10.Prisms, pyramids, and spheres

are polyhedra.

12.A cube is a special type of

rectangular pyramid.

16.Margaret made a net from four

triangles. Name the solid figure

for her net.

Use the solid figures below to answer exercises 13–14.

13. Name each figure above. 14. Draw the net for each figure.


14. Make a table listing the number of edges, faces, and vertices
    for each solid figure in exercises 1–4 on page 362. Write an
    equation to describe the relationship between the number of
    edges and the sum of the vertices and faces of a polyhedron.
