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.

(15 pts) The heavy duty foil is .0010 cm thicker than the regular foil .0024-.0014 .0010 cm .0014 7 ratio .0024 12 Is this what you would expect If consumers are paying 1/3 more for the heavy duty type of foil, are they getting their moneys worth (15 pts) I did not expect it to be such a small difference because the heavy duty foil feels so much thicker than the regular. 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. Part V Write out the supplies that you needed to complete your lab procedure for separation. (10
