cbrt()

The cbrt() function returns the cube root of the argument.

Syntax

std::cbrt(n)

Example

Use cbrt() to find the side lengths of a 27 m³ cube:

#include <iostream>
#include <cmath>

int main() {
  double V = 27;
  double side;

  side = std::cbrt(V);

  std::cout << "A cube with a volume of " << V << " has a side length of " << side << "\n";
}

This results in the following output:

A cube with a volume of 27 has a side length of 3
