The present dimensions of the candy bar are 15 cm in length, 6 cm in width, and 2 cm in thickness. The CEO has asked your consulting firm to come up with the best way to shrink the candy bar. Because millions of dollars are riding on this decision you will need to find all answers in centimeters correct to three decimal places.
6. Consider reducing two (but not three) of the dimensions by the same number of cm. What would the new dimensions be in each case? (There are three possibilities; in each case you want the volume to be 15% less than the original volume. (i.e., you want it to have the volume found of 153.)
7. Consider reducing all three dimensions by the same number of cm. What would the new dimensions be? (Once again, you want the volume to be 153.)

Since V= l*w*d regardless of what we do, we use this. Let x be the amount of shrinkage.
6. (one possibility) 153=(15-x)(6-x)(2)
7. 153 = (15-x)(6-x)(2-x)
Expect multiple roots and you will discard the extraneous one.
