Right square pyramid with equilateral trianglar faces.  The sides and base are all 8. d is in the middle of the pyramid with a dotted line down the middle.  I am just super confused on how to do this problem.  I have tried to find the formula in my textbook but can't figure it out.  Thank you </SPAN>\n" );
