lock uses 3 numbers as an unlock code, each of which can, be 0 to 10 . If there are no restrictions on the numbers, how many
ossible unlock codes are available?

With each of the three numbers in the unlock code having the option to be any integer from 0 to 10, you essentially have 11 choices for each number — 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. To find the total number of possible unlock codes, you multiply the number of choices together:

11 choices for the first number × 11 choices for the second number × 11 choices for the third number equals 11 × 11 × 11 = 1331 possible unlock codes!

So, you’ve got a whopping 1331 combinations to choose from! Happy unlocking!
