Answer: 1000

Step-by-step explanation:

The number of combinations is equal to the product of the number of options for each tumbler.

Each tumbler has 10 possible numbers, and we have 3 tumblers, then the number of combinations is:

C = 10*10*10 = 10^3 = 1000

We have 1000 possible codes for the lock.
