The capacity of the alphabet is 256. How many KB of memory would be required to store 160 pages

The capacity of the alphabet is 256. How many KB of memory would be required to store 160 pages of text with an average of 192 characters per page?

The problem is solved by the formulas I = k * i and N = 2 ^ i (2 to the power of i), where N is the cardinality of the alphabet.

By condition: N = 256, k = 160 * 192 (total characters in the document). It is necessary to find I. First we find i. 256 = 2 ^ 8 (2 to the 8th power). i = 8. Then I = 160 * 192 * 8 = 245760 bits = 30720 bytes = 30 KB.
