NOTE: Remember to discuss lenth, width and height in your description of what is happening.
HINT: For your shortcut use letters to represent the numbers. Say there are l cubes in a row, w rows, and h layers.

Fill in the table with the data you collected from the previous exercises. Then describe a shortcut for finding the number of cubes.
NOTE: The term "shortcut" on the worksheet is used in place of the more traditional term formula. Some helpful questions for finding a shortcut:  How many inch cubes are in each layer?  How do you find this number?  How many layers are there?  What would you do with these numbers to find the number of cubes?
