To find the total number of clock strikes in 12 hours, add the strikes made at each hour.
The clock strikes 1 time at 1 o’clock, 2 times at 2 o’clock, and continues this pattern up to 12 strikes at 12 o’clock.
So the total is:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78.
Answer: 78 strikes.
This is the sum of all whole numbers from 1 through 12.
