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. \(x + y\)
B. \(\frac{x + y}{3}\)
C. \(\sqrt[3]{x+y}\)
D. \((x + y)^3\)
E. \(\frac{\sqrt[3]{x+y}}{3}\)
A. \(x + y\)
B. \(\frac{x + y}{3}\)
C. \(\sqrt[3]{x+y}\)
D. \((x + y)^3\)
E. \(\frac{\sqrt[3]{x+y}}{3}\)

Let the sides and also the height be a each, therefore \(V=a^3\)
Volume is also equal to x+y, therefore \(V=a^3=x+y......a=\sqrt[3]{x+y}\)
C is wrongly written, it should be 3rd root.
