How many CDs of 700 MB will be required to accommodate information that fully occupies a 120 GB hard drive.

Let’s determine how many CD-media are required in order to place on them information that completely occupies a 120 GB hard drive, when we know from the conditions of this task that the volume of each CD-media is 700 MB:

1 GB = 1024 MB;

120 GB = 1024 * 120 = 122880 MB;

122880: 700 ≈ 175.54.

Rounding up to an integer, we get 176 CDs.

Answer: To accommodate such a volume of information, 176 CD-carriers are required.
