>>>In my understanding, that is the correct solution. Let me detail the solution, for the remaining participants.
>>>
>>>Two similar objects have a volume that is proportional to the third power of any linear measure (height, circumference, etc.). This can easily be verified for some shapes for which you know the formula, such as a sphere, a cube, or a pyramid, but it is valid in general.
>>>
>>>Therefore, 8000 tons / 1e9 = 8e6 kg. / 1e9 = 0.008 kg. = 8 grams.
>>>
>>>(1e9, or 1000 millions, is the ratio - 1:1000 - to the third power)
