Use Pythagoras theorem to find the slope of the square pyramid
to find the slope you must image the right triangle formed
 the base of the right triangle is half the length of the base of the
pyramid
thus
   l² = h² +( b/2)²      where  l = slope
                                           h = vertical  height
                                           b = length of base
 l² =  463²+ 385²                  / 770/2 =  385
l =  √(214369 + 148225)
