Question 979221
<pre>
Let's draw a cube:

{{{drawing(400,400,-1,6,-1,6,
line(0,3,3,3), line(3,3,3,0),line(3,3,5,5),
line(0,0,3,0),
line(5,2,3,0),
line(5,2,5,5),
line(2,5,5,5),
line(2,5,0,3),
line(0,0,0,3),
green(line(0,0,2,2),
line(2,2,5,2),
line(2,2,2,5)) )}}}

Count the edges.  How many at the top?
How many around the sides? 
Hom many at the bottom?
How many is that altogether?

So divide the given sum of all the edges by the total
number of edges to find the length of each edge.

Then use the formula 

{{{VOLUME=EDGE^3}}} to find the volume.
