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
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

Hi,
Archit3110
Why do you say "Depth of the cube pool would be equal to the volume of the cube"?
Shouldn't the depth be cube root of the volume? Considering V= S(cube) so S= V^1/3
What am I missing? Shouldn't the answer be (x+y)^1/3 ?? I can't find that in the options.
