there is only 2 numbers which are greater than 7 i.e. 8 and 9. ∴ there is 2 possibility for first place.
For the remaining 3 digits there is 9 possibilities (including 1 which would left after choosing 1 from first place )
No of ways for the alarm code beginning with a number greater than 7= 2 P 1 x 9 P 3
<em>Total ways of code with 4 digits= 10 P 4.</em> Hope this helps :)

Step-by-step explanation:
Given: A tissue box has a length of 10 inches, a width of 6 inches, and a height of 3 inches.
