Bloomberg had also published this article over a year ago:

"So far, Israeli air strikes have left more than 42 million tonnes of debris across the Strip, according to the UN. That’s enough rubble to fill a line of dump trucks stretching from New York to Singapore. [...]

The majority of the debris is destroyed housing, and its distribution across the Strip roughly mimics Gaza’s population density before the war."
