How Many Tons of River Sand in One Brass? (Clarification)

The question mixes units incorrectly.

• Brass is a copper-zinc metal alloy—measured in kg, lbs, or tonnes of metal.
• River sand is a sediment—measured in volume (m³, cu yd) or mass (tonnes).

There is no conversion between "brass" and "river sand." If you meant "brass" as a traditional Indian volume unit (1 brass = 100 cubic feet ≈ 2.83 m³), then:

• Dry river sand density ~1.6 t/m³ → 1 brass ≈ 4.5 metric tonnes.
