Question

There are 10 computers in the computer lab that each have 20 GB hard drives. How many bytes (

b. of disk space do we have in the computer lab in total.

Answer 1

Hence, total number of bytes in 10 computer is 2 ×
`10^(11)` Bytes.

Step-by-step explanation:

One computer have 20 GB hard drive.

1 GB =
`10^(9)` Bytes

20 GB = 20 ×
`10^(9)` Bytes

Thus, one computer has 20 ×
`10^(9)` Bytes.

There are 10 computers in the computer lab that each have 20 GB hard drives.

So, total Bytes on 10 computer is given by,

1 computer = 20 GB

10 computer = 200 GB

Thus 10 computer have total 200 GB.

As given above,

20 GB = 20 ×
`10^(9)` Bytes

This is number of bytes in 1 computer.

So, in 10 computer number of Bytes are as follows,

10 × 20 GB = 10 × 20 ×
`10^(9)` Bytes

200 GB = 200 ×
`10^(9)` Bytes

200 GB = 2 ×
`10^(11)` Bytes

Hence, total number of bytes in 10 computer is 2 ×
`10^(11)` Bytes.
