Megan needs to distribute anonymous blood pressure test results for 10 volunteers over the Internet. Before she does so, what should she do to ensure that private information about her and her medical practice is removed and that the file is accessible to as many people as possible?

Hypothesis: volumes of both figures are equal.the volume of  figure 1 is: .the volume of figure 2 is: .since , you can conclude that and . so, .volumes of figures are equal only when an angle in the basis is right (then figures will be the same), in another cases volume of figure 1 is less than volume of figure 2.the hypothesis was not correct in all cases.

Ithink the answer is both.
