An article typed on a computer contains 64 pages, each page contains 40 lines, each line contains 40 characters.

An article typed on a computer contains 64 pages, each page contains 40 lines, each line contains 40 characters. Determine the size of the article in KOI-8 encoding, in which each character is encoded in 8 bits.

First, let’s find the number of all characters in this article.

K = 40 * 40 * 64 = 102400 characters.

Next, we will find the informational volume of the article.

I (informational amount of text) = K * i (informational amount of one character of the text) = 102400 * 8 bits = 819200 bits = 819200/8 bytes = 102400 bytes = 102400/1024 kB = 100 kB.

Answer: 100 KB.
