How much would a city block weigh if Super-Man could lift it without any buildings or structures on top?

 Determining the weight of a city block without buildings or structures involves several considerations. Firstly, the composition of roads and sidewalks varies, with materials like asphalt, concrete, and pavement contributing to the overall weight. Without specific details on the city block's dimensions and materials, it's challenging to provide a precise weight. Superman's strength, as depicted in comic books, is often portrayed as virtually limitless, enabling him to lift massive objects. However, the absence of a standardized weight for a city block and the fictional nature of Superman make it difficult to calculate an exact figure. Ultimately, the weight would depend on the specific characteristics of the city block in question.
