The answer is A:

Because the only difference between the rest of the answer choices are the lower and upper quartiles, that is all you need to find. In order to do so you find the median for the first half (lower quartile) and then find the median for the second half. In this case it is 29 (Q1) and 58 (Q2)

A prism is dilated by a factor of 1.5. How many times larger is the volume of the resulting prism than the volume of the origina
Margarita [4]
By the term dilated we mean to say that the dimensions of the new polyhedron is increase to a certain size by that times. For the volume, this dilation scale should be cubed in order to determine the number of times the volume of new figure is larger than the original.
                                    r = (1.5)³
                                      = 3.375
Thus, the volume of the new prism is 3.375 times larger than the volume of the original prism.
