How many bytes are there in 256 kbytes?

256000 bytes.

Explanation:

One Kilo byte(KB) consists of 1000 bytes.So the number of bytes in 256 kilo bytes is :-

1 kilobyte = 1000 bytes.    

256 kilo bytes = 256 x 1000 bytes.  

256 kilo bytes = 256000 bytes.  

Also 1 bytes consists of 8 bits.

1 kb = 1000 bytes.

1GB Giga byte = 1024 kilo bytes.

1 TB Tera Byte = 1024 Giga Bytes (GB).  

Hence the answer to this question is  256,000 bytes.

so much for the extra points :
