Interactive tool for practicing comparing two lengths, areas, and volumes. It is VERY TRICKY to judge how area and volume change with size. This tool gives you good practice. Good for physics problems to do with pressure, gravity, and other places where area or volume are important.

Explore size estimation in one, two and three dimensions! Multiple levels of difficulty allow for progressive skill improvement.
