Answer:
0.078 kilograms.
Step-by-step explanation:
In terms of grams, London's paperclip sculpture weights about 78 grams.
Now, converting grams into kilograms, we can take that 1 gram makes 1000 kilograms.
Now,
1 gm= 1000 kg
So,
78 gms = 78÷1000
= 0.078kgs.
Therefore, London's sculpture made from paperclips weighed 0.078 kilograms.
