### Constructing a Sphere out of Paper

Subject: Flattening a sphere (constructing a sphere out of paper)

Hi,

I'm hoping you might be able to help me. I'm working on a school
project and can't seem to find the answer anywhere. The assignment is
to construct a 3D 9"-diameter sphere out of paper.

Isn't there some standard format or template for figuring this out?
Thank you.

Hi Camille,

What a challenging project!

chunks:

And a friend of mine has some pictures and an explanation of why you
can't make a sphere out of paper. Basically, a sphere is REALLY curved
(this file is in PDF format):

You can also see a discussion of a math teacher's approach at

Making Hemispheres out of Paper
http://mathforum.org/library/drmath/view/55168.html

Basically, this math teacher decided to make a polyhedron with a
number of sides. A polyhedron is a 3D shape made of polygons. The cube
and pyramid are the most common polyhedra, but there are lots of
others. You can see the next two links for pictures and info about
constructing polyhedra.

Hope this helps! Please let us know how the constructing goes. Write
back if you think we could be of more help.
