Question 1078119
.
<pre>
For your info:


1.  The prism DOES NOT have elements called "side lengths".
    It has elements called "edge lengths" instead.


2.  A triangular prism has three edges at the base. 
    You gave the lengths for only TWO edges.


After these my notes please deside whether your post has any sense.

It only demonstrate your VERY LOW knowledge of terminology in Geometry,


as well as non-willing (or absence of skills) to write the condition accurately.
