3[3(5/15)+11+9=30
This question is wrong, and I can prove it too. There are boxes, and every one to be filled with odd number.
every odd number is of the form :-
2a+1
2b+1
2c+1
2d+1
2e+1
2f+1
2g+1
2h+1
2i+1

I have taken 9 cases because your question has 9 boxes.
Now on adding all of them, we get 2 (a+b+c+d+e+f+g+h+i) + 9 = 2(a+b+c+d+e+f+g+h+i+4) + 1
Hence proved, that it will always yield an odd number.
the answer is 5.75+ 5.75 + 5.75 + 5.75 +7= 30
3!+3!+3!+3!+3!=30
