Question

How many optical disc of 720mb storage capacity are needed to store 20gb storage of hard disc​

Answer 1

To store 20GB on 720MB optical discs, one would need 29 discs, as you can't use a fraction of a disc and rounding up to the nearest whole number is necessary.

Step-by-step explanation:

To calculate the number of 720MB optical discs needed to store a 20GB hard disc capacity, we must first make sure both units of storage capacity are in the same units. Since there are 1024 megabytes in a gigabyte, we can convert 20GB into megabytes:

20GB = 20 × 1024MB = 20480MB.

Now, we will divide the total megabytes by the capacity of one optical disc:

20480MB ÷ 720MB/disc = 28.444... discs.

Since you can't use a fraction of a disc to store data, you would need 29 optical discs to store the entire 20GB because you would need to round up to the nearest whole number.

Answer 2

The answer would be 700 because you would just subtract the amount u need it’s very simple because of the storage amount
