28. How many standard sheets of paper will be required to print all numbers from 1 to 1000000 inclusive, if printing on one side of the sheet? Each sheet has 30 lines with 60 characters each, and there are intervals between numbers, each equivalent to two characters.
28. For printing single-digit numbers, 9 characters are required; for two-digit numbers - $180(2 \cdot 90=180)$; for three-digit numbers $-2700(900 \cdot 3=2700)$; for four-digit numbers $36000(4 \cdot 9000=36000)$; for five-digit numbers $-450000(5 \cdot 90000=450000)$; for six-digit numbers $-5400000(6 \cdot 900000=5400000)$ and one seven-digit number (1000000) 7 characters, and in total $9+180+2700+36000+450000+5400000+7=5888896$. The intervals between numbers will take up: $2.999999=1999998$ characters. Therefore, a total of 7887894 characters are needed $(5888896+1999998=7887894)$. On one sheet (page), 1800 characters can fit $(60 \cdot 30=1800)$. Since

$7887894: 1800=4382$ (remainder 294), a total of 4383 sheets of paper are required.
