There are varying amounts of bytes on different types of CDs. There is no fixed or allowed number of megabytes on one CD. The general pattern is: the more money the CD is worth, the more memory is available on the CD.
The average is around 700 mb, but it can differ greatly.
100000000000 100000000000 100000000000
there is 1000000 mega bytes in a terabyte
0.075
there are no giga bytes in 10 mega bytes. there are 1024 mega bytes in a giga byte
1024 Mega Bytes = 1 Mega Kilo Bytes !
Almost certainly that would be a CD-ROM.

33.13 megabytes.
1024 mega bytes
128 megabytes equals 134,217,728 bytes.
