Alex Ar [27]

Answer:

5789 digits

Step-by-step explanation:

Given that the number of pages ares: 1,724

As we know that:

(from 1 - 9) there are 9 one-digit numbers
(from 10- 99) there are 90 two-digit numbers
(from 100 - 999) there are 900 three-digit numbers
(from 1,000 - 1,724) there are 725 four-digit numbers

So the total are:

$= 9(1)+90(2)+900(3)+725(4)\\\\= 9+180+2,700+2,900\\\\= 5,789\ digits$
