Problem
A right rectangular prism 
(i.e., a rectangular parallelpiped) has sides of integral length 
with 
A plane parallel to one of the faces of cuts into two prisms, one of which is similar to 
and both of which have nonzero volume. Given that 
for how many ordered triples 
does such a plane exist?
