Tags: See more , See less 8 Answer Add Tags Answer Interview Answer 2 Answers ▲ 0 ▼ Decrease. Interview Candidate on Jun 21, 2011 ▲ 7 ▼ This is actually wrong. The water level actually increases.The amount of water displaced when out of the boat is equal to the volume of the rock, but when the rock is moved to the boat it is based on the mass of the rock. Since the rock is denser than water the water level rises.
