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.

This is what I have so far, it compiles but when I ask total(3,T) it replys no. Any suggestions would help. Thanks.

```
total(0,T).
total(N,T):-
N>0,
N1 is N-1,
T1 is N*N*N,
total(N1,T1),
T is T+T1.
```
