THE REGULAR SOLIDS
(VOLUME OF) PAGE
####
A regular solid is a lump that has all sides the same length, all faces the
same shape and the same number of sides meeting at every corner. There are only
five of them and they are shown here. We were asked how to find the VOLUME of these
solids. (Although why anybody wants to know the volume of an icosahedron is a
complete mystery to us.)

Here's a bit of page 121 from Vicious Circles. (This is
the MM book that tells you all about regular solids.) We've
stuck the volume formulas on next to each solid.

"s" = the length of any side of the solid.

You'll notice that each formula has a set of numbers at the front
and they all have s^{3} at the end!

These formulas were found by our friend Hu Yi Jie on the amazing website:
Math Forum.
