Answer: 5.6 kilograms.
Explanation:
We know that 1,000 paperclips have a mass of 1 kilogram.
Therefore, one paperclip has a mass of 1/1000 kilograms, or 0.001 kilograms.
To find out how many kilograms 5,600 paperclips have, we can multiply the mass of one paperclip (0.001 kilograms) by the number of paperclips:
0.001 kilograms/paperclip * 5,600 paperclips = 5.6 kilograms
Therefore, 5,600 paperclips have a mass of 5.6 kilograms.
