Answer:
We need approximately 1667 floppy disc to store bytes of data.
Step-by-step explanation:
We are given the following information in the question:
A floppy disc can store 1440000 bytes of data.
We have to convert 1440000 in a standard form.
Standard Form:
- Standard form is a way of writing down very large or very small numbers easily.
- It helps us to express large numbers in powers of 10
The standard form can be written as:
We have positive power of 10 because we have to move to the right of the decimal point.
A hard disc can store bytes of data.
Number of floppy disks needed to store the bytes of data =
Thus, we need approximately 1667 floppy disc to store bytes of data.
