Aprogram is divided into 3 blocks that are being compiled on 3 parallel computers. each block takes an exponential amount of time, 5 minutes on the average, independently of other blocks. the program is completed when all the blocks are compiled. compute the expected time it takes the program to be compiled.

It should be by long pressing on the name of an answer if not i'm on a pretty old phone so it might be different for me

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.
