Area and Volume Calculator
Building: Easy
Program: Advanced

This simple device can be used to calculate length, area, and volume by rolling the wheel along surfaces, similar to an electronic "Rolling Tape" device.  The NXT does the math and displays the results on the screen in both metric and English units.
