Question from don: If the earth were covered completely with water (over Everest) how many gallons would it be?? |
Don,
According to Wikipedia the mean radius of the earth is r = 6371 km. Assuming the earth is a sphere you can use this value to calculate it volume in cubic kilometers using volume = 4/3 π r3. Look up the height of Mount Everest in kilometers, add this to r and calculate the volume of a sphere of this radius. Subtract the two volumes to calculate the volume of water in cubic kilometers. Suppose the result is V cubic kilometers. Finally type into Google V cubic kilometers in gallons.
