Answer:
Hence, total number of bytes in 10 computer is 2 × [tex]10^{11}[/tex] Bytes.
Explanation:
One computer have 20 GB hard drive.
1 GB = [tex]10^{9}[/tex] Bytes
20 GB = 20 × [tex]10^{9}[/tex] Bytes
Thus, one computer has 20 × [tex]10^{9}[/tex] 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 × [tex]10^{9}[/tex] Bytes
This is number of bytes in 1 computer.
So, in 10 computer number of Bytes are as follows,
10 × 20 GB = 10 × 20 × [tex]10^{9}[/tex] Bytes
200 GB = 200 × [tex]10^{9}[/tex] Bytes
200 GB = 2 × [tex]10^{11}[/tex] Bytes
Hence, total number of bytes in 10 computer is 2 × [tex]10^{11}[/tex] Bytes.
