Practice what we learned in class about polyhedron with a convenient
box:
Find a convenient box (not too large) and do the following for it:
- Tell it's geometric name. You may find it helpful to look
at the pictures of prims and pyramids on page 206 of the Van de Walle
book. This slideshow
is good too.
- Count and tell how many faces it has
- Count and tell how many vertices it has
- Count and tell how many edges it has
- Make a net for your box. If you have a big box, make a
scale drawing of your box to turn in (so it will fit on one sheet of
paper). You might want a big net for yourself, to use for step 6
- Use your net* and your tiles to approximate the surface area of
your box (tell me the surface area)
- Use your box, and your linking cubes to approximate the volume of
your box (tell me the volume)
* A cool thing to do with nets is to go the the web site I
showed in class. Pick any polyhedron, and on the Unfold tab,
click Enable unfold, then drag the slider to see the net fold into the
polyhedron and unfold again!
