Since your measurements are in feet, $V$ will be in cubic feet. I am a Mac user so if I wanted the volume in gallons I would ask Siri "Hey Siri what is $V$ cubic feet in gallons?" To determine the actual volume of water in the well you would have to use the calculation above with $h$ being the height of the water in the well. Penny
