Sand is heavier than water when both things are of equal volume. Sand has a density of 80 and 100 pounds per cubic foot, while water has a density of 62 pounds per cubic foot. The water’s density is dependent on its temperature.
These calculations result in sand densities between 1,281 and 1,602 kilogrammes per cubic metre and water densities between 958.4 and 999.97 kilogrammes per cubic metre. Wet sand weighs approximately 120 pounds per cubic foot, while packed wet sand weighs approximately 130 pounds per cubic foot. Water is the most dense at 39 degrees Fahrenheit and least dense when it is frozen.
