Question

A hard disk can store `2.4 * 10^9` bytes of data. How many floppy disks are needed to store `2.4 * 10^9` bytes of data?

A floppy disk can hold 1440000 bytes of data.

Answer 1

`1,667`

Explanation:

Floppy disk holds `1.44xx10^6` bytes

`(2.4xx10^9)/(1.44xx10^6)=2.4/1.44 xx10^3= 1.6bar6xx10^3=1666.bar6`
but since you can't have a fraction of a floppy disk
you will need `1,667` of them.

(In actual practice, you would need more than this; the `1.44` Mbytes on a floppy includes a higher fraction of overhead space than would typically be used on a hard disk).
