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 {12058680} grams of paint.");

Can anyone please help me to solve it?

It is exactly 1 symbol that is missing. You forgot to add ‘$’ in front of the string.

int a = 317;
int b = 317;
int c = 6;
int d = 20;
int result = abc*d;
Console.WriteLine(" I need " + result+ grams of paint.");
