myText=Shown above is an example of how the next exercise will look. For this exercise (continued on the next page), count the squares to find the surface area that the beam covers. Count any square that the light hits as one millimeter squared, including the ones that are only partially lit. After counting the squares, type your answer in the box above and click the "OK" button to continue on to the next page. Following these directions, the example above has an area of 228mm squared. *Note how the angle of the light corresponds with the area it covers.
