Say, the sandwich is divided into 3 lengths A, B and C. Now the middle piece is 8in. longer than the shortest piece. Let the longest piece be A (doesn't matter if it's A or C since you can rotate the sandwich around and it'll be at the other end). The shortest piece is C. 

Using the information given, we can now make some equations:
B=4+C
C=A-8
Now together, A+B+C=63, so do you know what to do from there?
