Please help me with the task: Paint the Dominator

Hello, I’m working on this task:

The biggest machine known to us is a huge cube, measuring 317 meters in each direction, and it is called “Dominator.” To stop Dominator, we plan to paint it with a machine-destroying paint. Write a program that calculates how much paint we will need to totally paint all six sides of Dominator, if painting 1 square meter takes 20 grams of paint. You have studied geometry, haven’t you? Output the result using string interpolation in the format:

I need ** grams of paint.

Here is my code:


public static class PaintTheDominator
{
   public static void Main()
   {
       Console.WriteLine("I need { "317 * 317 * 6 * 20"} grams of paint.");
   }
}

Can anyone please help me to solve it?
