An empty, cube-shaped swimming pool is filled part way with x cubic feet of water. It is then filled the rest of the way with y cubic feet of chlorine. Which of the following, in feet, expresses the depth of the swimming pool?

A. x+yx+y

B. x+y3x+y3

C. x+y‾‾‾‾‾√x+y

D. (x+y)3(x+y)3

E. x+y‾‾‾‾√33x+y33

Depth of the cube pool would be equal to the volume of the cube, given that the cube is filled first with x ft3 water and then yft3 of chlorine hence total volume would be ( x+y)^(1/3), option C
