CD-ROM Storage Space

According to a Science News Article, a CD-ROM could squeeze 100 million bits into each square centimeter of recording surface. Using an actual CD-ROM, calculate the recording surface of the CD-ROM in square centimeters. Make sure to give a detailed explanation of how you calculated the area. Using the area calculation, calculate the approximate number of bits that can fit on a CD-ROM. Calculate the approximate number of "nibbles" (a nibble is a group of four bits) that can fit on a CD-ROM and calculate the approximate number of "bytes" (a byte is a group of eight bits) that can fit on a CD-ROM.

Text characters can be stored on computer media. Each character or space takes one byte of memory, for example the first four sentences of this project require about 550 bytes. If the average word is 5 characters long and a space separates words, how many bytes does a computer picture take if "a picture is worth a thousand words?" If this is correct, how many pictures would fit on a CD-ROM?
