Of course there are two answers. Sometimes you will see people dividing by 1,000, so the answer would be 5.6MB.
However the technically correct answer would be to divide by 1024, since these things are measured in powers of 2, and that answer would be 5.6MB.
Which, of course, rounds off to the same number, unless you carry the decimal point further out.
1126.4 mb * 1024 kb/mb = 1,153,433.6 kb
