solution: we know that there are 25 prime numbers are between 1-100 and 168 prime numbers less than 1000. 100 x 100=10000(5 digits) 999 x 999=998001(6 digits) 1000 x 1000=1000000(7 digits) so our answer should be same as the number of prime numbers between 100 to 999. hence, 168-25=143. 143 prime numbers will be there less than 1000 whose square has 5 or 6 digits.

999 are whole.
Well, sweetheart, Armstrong numbers, also known as narcissistic numbers, are numbers that are equal to the sum of their own digits raised to the power of the number of digits. In this case, the Armstrong numbers between 100 and 1000 are 153, 370, and 371. So, there you have it, darlin'. Hope that satisfies your curiosity.
Numbers above 99 and under 1000 are 3-digits, all 900 of them.

Infinitely many. The number pi , for example, is between 1 and 1000 and, since pi is a transcendental number, it contains infinitely many digits. Plus, there are all the irrational numbers - each with infinitely many digits, and all the rationals with recurring decimals - again with infinitely many digits.
numbers between 100 and 1000 = 900 numbers between 100 and 1000 which do not have digit 6 in any place = 8 x 9 x 9 = 648 Unit digit could take any value of the 9 values (0 to 9, except 6) Tens Digit could take any value of the 9 values (0 to 9, except 6) Hundreds digit could take any value of the 8 values (1 to 9, except 6) numbers between 100 and 1000 which have atleast one digit as 6 = 900 - 648 = 252
