Now if I was a little mathematician that had not yet had too much
book-larning I would write down the formula for the volume and start
filling in the numbers.  Make a table of the dimension x vs the

But Yehuda wanted me to use Logo.  So I would write the following
simple little formula and let it do its thing.  Dale
