The lock has 3 different cylinders that can take up to 70 possible numbers. The possible combination of each cylinder would be 70!
The order of cylinder would be important because the password on 1st cylinder can't be used on cylinder 2. The calculation would be:
possible lock combination= 1st cylinder possible combination* 2nd cylinder possible combination * 3rd cylinder possible combination
possible lock combination= 70!*70!*70!
It will take 80 minutes to fill the pool 20x4=80
Answer:
I think the answer is 70
Step-by-step explanation:
40 + 15 = 55 and when you add 15 to 55 you get 70 but this might not be right!
