What is the total weight of all the man made structures in the city of Moscow.?
Yes, mine is inspired by the best answer so far: You’ll first have to calculate the total surface area of Moscow in Metres – this is an easy Area of a Circle with known radius question. Then calculate the Average height of all the buildings taking into account the Total surface area of non-building areas including parks, canals, streets, memorials,…. Then Average the Weight of Building Materials per cubic meter (using a weighted average involving all the building materials in use and involving the many contents of these buildings).

After all, even the sewer pipes and all the cables are man-made, and 99% of the trees, bushes and garden flowers, the traffic poles,…. . So you Minus the Streets from the Total Surface area, Times it by the height then times it by the average Weight. Then you add on the non-buildings component, where you also had an estimation. Then stir vigorous
