1. The problem statement, all variables and given/known data The question wants me to use this formula: ((4pi)^(1/3))((3v)^(2/3)) You have filled two round water balloons with water. One balloon contains twice as much water as the other balloon. Compare the surface areas of the two water balloons using the given formula. 2. Relevant equations None 3. The attempt at a solution I don't know where to start And I Don't Know where they got the answer from. The book gave me a final answer as: The balloon with twice as much water will have about 1.59 times the surface area of the balloon with less water.
