How much water do you have?

Answer 1

Scientists estimate that we have 326 million cubic miles of water. That means if I had a cube one mile by one mile by one mile and filled it with water that would be one cubic mile. So,if I had 326 million of those cubes (all filled with water) then that would be about the same amount of water on the Earth. About 72% of Earth is covered in water but 97% of that water is useless because it is salty.3% of water is left but 70% of 3% is frozen so we only have less than 1% of the Earth's water.
