Problema Solution
Once cubic foot of water equals about 7.5 gallons. How many gallons of water are in this lake?
Answer provided by our tutors
Since each cubic foot is 7.5 gallons, and we have 2.72*10^9 cubic feet, we'll just multiply:.
Again, we want the first number to be between 1 and 10, so this will turn into 2.04*10^10 gallons.
