4 cm.

Let the middle-sized piece be x cm, then longest piece=3x and shortest piece=(3x-23) cm.
Total length=3x + x + (3x-23) = 40 cm.
=> 7x=63 or x=9 cm.
Hence length of shortest piece=3x-23 = 3*9 - 23 = 4 cm.

let the length of longest piece is 3x and the medium sized piece is x and the smallest piece is 3x -23.
Then according to question:-
3x+x+3x-23=40 ==> 7x=40+23 ==> 7x=63 ==>
x=9;
Longest piece is: = 3x=27;
Medium sizes piece is: x=9;
Shortest piece is 27-23 =4;
