Is there a particular beach you're studying? Are you just talking an average of all white sand beaches? Are we even talking beach sand, because deserts have sand too... sand is…
That depends on the sand. Choose one of these densities: Sand, wet - 1920 kg/m³ Sand, wet, packed - 2080 kg/m³ Sand, dry - 1600 kg/m³ Sand, loose - 1440 kg/m³ Sand, rammed - 1680 kg/m³ Sand, water filled - 1920 kg/m³ Now put it into the following formula: kilograms of sand / density = cubic meters of sand
