Answer:
11
Step-by-step explanation:
The number is divisible by 9 since the square root is divisible by 3. A+B+C+8+3+5 is a multiple of 9. There are only two sums that are divisble by 9. The number either adds up to 36 or 27. A+B+C add up to 20 or 11. 20 doesn't work since its not a square so the answer is 11.
