title: Prolog and Recursion
body: <p>I'm new at prolog and recursion in general.
    Given the size of each cube is represented by the cube number.   For example, total_cube_volume(3, T), will have 3 cubes: the first cube will have 1 inch on each side, the second cube will have 2 inches on each side, and the third cube will have 3 inches on each side.  Therefore, the total volume for this problem is 36. </p>
  
  <p>This is what I have so far, it compiles but when I ask total(3,T) it replys no. Any suggestions would help. Thanks.</p>
  
  <pre><code> total(0,T).
  
   total(N,T):-
       N&gt;0,
       N1 is N-1,
       T1 is N*N*N,
       total(N1,T1),
       T is T+T1.
