There are 10*10*10 possible combinations, or 1000.
000 is the first, and 999 is the last. If you don't remember the code you will need to go through /every/ combination. Just start with 000, then try 001, and so forth. Count your way from 0 to 999, and you will get it. If you try 40 a day it will take you less than 1 month to crack the code.

u will have 720 number combinations... since 0-9 has 10 numbers all in all and u only have 3combinations out of the 10 numbers... instead of combinations,u have to use permutations... since in combinations the 3number combination like 123 would be just the same inas 321 or 213... but in permutation, 123 could never be 321 in the case of ur code... so... thats nPr on ur calculator... try to check... n is 10 while r is 3 so its 10P3=720...

The possible combinations can be from 000 to 999, or 1000 total. The last time this happened to me, it took about 2 hours before I got the right combo.

No matter u know the probability or combination no's, u will not be able to open the box without remembering the actual combination

After you find the code - don't forget to write it on the box somewhere.

You can always cut the lock and buy a new one if you are in a hurry.
