How can I calculate the total surface area of a cube with a volume of 125 cm³ in C#? Please provide the answer in cm². I found this formula online: A = 6√(V²/6). Can you provide a C# code that uses this formula to calculate the surface area of the cube?

Sure, I'd be happy to help you with this. Here's a C# code that implements the formula you provided:

```csharp
using System;

class Program
{
    static decimal CalculateSurfaceArea(decimal volume)
    {
        // You can't calculate the square root of a negative number, so
        // check if it's a positive number first.
        if (volume <= 0)
        {
            throw new ArgumentException("Volume cannot be negative.");
        }

        // Use Math.Pow() to raise the volume to the power of 2/3.
        decimal sideLength = Math.Pow(volume, 1 / 3);

        // Calculate the surface area using the formula.
        decimal surfaceArea = 6 * (decimal)Math.Sqrt(volume * 2 / 3);
        return surfaceArea;
    }

    static void Main(string[] args)
    {
        // Prompt the user to enter the volume.
        Console.Write("Enter the volume of the cube (in cubic centimeters): ");
        decimal volume;

        // Check if the input is a number and if it's positive.
        while (!decimal.TryParse(Console.ReadLine(), out volume) || volume <= 0)
        {
            Console.Write("Invalid input. Please enter a positive number: ");
        }

        try
        {
            // Calculate the surface area and display the result.
            decimal surfaceArea = CalculateSurfaceArea(volume);
            Console.WriteLine("The surface area of the cube is {0:F2} square centimeters.", surfaceArea);
        }
        catch (Exception exc)
        {
            Console.WriteLine("An error occurred: " + exc.Message);
        }
    }
}
```

This code first calculates the side length of the cube using the formula `sideLength = sqrt(V / 6)^(3/2)`, and then calculates the surface area using `surfaceArea = 6 * sqrt(V * 2/3)`.

The code also checks if the input is a positive number and prompts the user to enter a valid input if it's not. If an error occurs during the surface area calculation, a message is displayed to the user.

Note that this code uses decimal types for the calculations, which can avoid truncation due to integer division. If you're using a newer C# version that supports C# 8's `using System.Numerics`.

```csharp
using System;
using System.Numerics;

class Program
{
    static BigDecimal CalculateSurfaceArea(BigDecimal volume)
    {
        if (volume <= 0)
        {
            throw new ArgumentException("Volume cannot be negative.");
        }

        BigDecimal sideLength = BigDecimal.Pow(volume, 1 / 3);

        BigDecimal surfaceArea = 6 * Math.Sqrt(volume * 2 / 3);
        return surfaceArea;
    }

    static void Main(string[] args)
    {
        Console.Write("Enter the volume of the cube (in cubic centimeters): ");
        BigDecimal volume;

        while (!BigDecimal.TryParse(Console.ReadLine(), out volume) || volume <= 0)
        {
            Console.Write("Invalid input. Please enter a positive number: ");
        }

        try
        {
            BigDecimal surfaceArea = CalculateSurfaceArea(volume);
            Console.WriteLine("The surface area of the cube is {0:F2} square centimeters.", surfaceArea);
        }
        catch (Exception exc)
        {
            Console.WriteLine("An error occurred: " + exc.Message);
        }
    }
}
```

Sure, I can help you with that. The formula you found online is indeed correct for calculating the surface area (A) of a cube given its volume (V). Here's a simple C# code snippet that uses this formula:

```csharp
using System;

class Program
{
    static void Main()
    {
        double volume = 125;
        double surfaceArea = CalculateSurfaceArea(volume);
        Console.WriteLine("The surface area of the cube is: " + surfaceArea + " cm²");
    }

    static double CalculateSurfaceArea(double volume)
    {
        return 6 * Math.Sqrt(Math.Pow(volume, 2/3.0));
    }
}
```

In this code, the `CalculateSurfaceArea` function takes the volume of the cube as an argument and returns the surface area calculated using the formula you provided. The `Main` function initializes the volume, calculates the surface area, and then prints it out.
