Final Jeopardy A. Science can be used by many people, not just scientists Your friend is building a model boat but is having problems getting it to float. You know that the density of water is about 1. 0 g/ml. Together with your friend you find the mass of the boat to be 500 g and the volume to be 450 ml. Based on these measurements you tell your friend that he must reduce the mass of his boat by at least 50 grams. He reduces the mass by 80 grams and his boat now floats.

Science is too complicated to be used to solve problems D. Science is not useful in everyday life
