The book is 160 pages on each page 40 lines of 60 characters to determine the amount of information contained in the book.

160 * 40 * 60 = 384000 bytes
If we were not told how many bytes are 1 character, then it is the minimum and weighs 1 byte
So we get 384000 bytes, convert to kilobytes and get 384000/2 ^ 10 = 375 KB
