# Ruby program to calculate the 
# cube root of the given number

print "Enter Number: ";
num = gets.chomp.to_f;  

CubeRoot = Math.cbrt(num);

print "Cube Root is: ",CubeRoot;

Output:

Enter Number: 27
Cube Root is: 3.0

Explanation:

In the above program, we read a floating-point number from the user using gets.chomp.to_f and calculated the cube root of the input number using Math.cbrt() function printed the result.
