The message is 2 pages, 32 lines each. Each line contains 30 characters. What is the size of the alphabet used if the entire message contains 720 bytes?
the whole message contains V = 720 B = 720 * 8 bits
K = 2 * 32 * 30 = 64 * 30 = 240 * 8
then from the formula V = Ki we find i: i = V / K = 720 * 8/240 * 8 = 3 bits
Find the cardinality of the alphabet N = 2 ^ i = 2 ^ 3 = 8
Answer: N = 8
