What is heavier water or sand?

Sand is heavier than water when the volume of both substances is equal. The density of dry sand is between 80 and 100 pounds per cubic foot, whereas water is 62 pounds per cubic foot. The density of water depends on its temperature.

These calculations convert to between 1,281 and 1,602 kilograms per cubic meter for sand and between 958.4 and 999.97 kilograms per cubic meter for water. Wet sand is about 120 pounds per cubic foot, and packed wet sand is 130 pounds per cubic feet. Water is the most dense at 39 degrees Fahrenheit and less dense when it is frozen.
