heavy duty samples as well as your dimensional measurements (length and width in cm) from Part III of this experiment, calculate the height, or thickness, of each sample of aluminum using the formula V l x w x h. In the formula, V stands for volume, l for length, w for width, and h for height. Once again, you will have to use your algebraic skills to manipulate the formula, to solve for height. You must show all your work.

I dont think we should be paying that much more for that bit of a difference but I do believe that the product is working.
