To find the real solution(s) of the equation

\[ p^3 = 125, \]

we start by taking the cube root of both sides.

The cube root of 125 is

\[ \sqrt[3]{125} = 5. \]

Thus, the equation

\[ p^3 = 125 \]

has the solution

\[ p = 5. \]

Now, we review the choices provided:

  • (Choice A) \(p = 3\) — This is not a solution.
  • (Choice B) \(p = -3\) — This is not a solution.
  • (Choice C) \(p = 6\) — This is not a solution.
  • (Choice D) \(p = -6\) — This is not a solution.
  • (Choice E) None of the above — This is the correct choice since \(p = 5\) is not listed.

Therefore, the correct answer is

\[ \text{(Choice E) None of the above.} \]
