How many sands in one dollar?

Could you please explain the concept behind the question, 'How many sands in one dollar?'" This inquiry seems to blend two entirely different concepts: currency and granular material. Dollars are units of monetary value, while sands refer to tiny particles of soil or rock. They exist in fundamentally distinct domains, with dollars representing economic transactions and sands being a natural element. It's unclear what kind of connection the questioner is seeking between these two entities. Is it a metaphorical reference to the value of something minute and numerous? Or is there a deeper cultural or historical allusion being made? Either way, it would be helpful to have some context or explanation as to why such a comparison is being drawn. Could you elaborate on the intention behind this question? Are you posing it as a rhetorical device to explore the relative worth of small units? Or is there a specific scenario or context in which you believe dollars and sands might be comparable? Thank you for clarifying.
