The sum of the number of digits in all the numbers between 31 and 400 inclusive is 1041.
There are 238 - 1 = 237 numbers between 1 and 238. To find the number of digits, we need to consider the range of numbers from 1 to 9 (1-digit numbers), 10 to 99 (2-digit numbers), and 100 to 238 (3-digit numbers). There are 9 one-digit numbers, 90 two-digit numbers, and 139 three-digit numbers between 1 and 238, totaling 9 + 90 + 139 = 238 digits.
I assume you mean significant digits. All digits are significant. A zero between other digits is always significant.

Answer: There are six. Answer: There is no such thing as "significant numbers". I assume you mean "significant digits". All digits are significant in this case - a zero (or more than one zero) between other digits is always significant.
