In the code, the user enters an integer and the code parses it and prints out the result. The user's number divided by the number of sides gives the result.
using System;
Console.Write("ΠΠ²Π΅Π΄ΠΈ ΡΠΈΡΠ»ΠΎ: ");
int a = int.Parse(Console.ReadLine());
Console.WriteLine("ΠΡΠ± Π²Π°ΡΠ΅Π³ΠΎ ΡΠΈΡΠ»Π° ΡΠ°Π²Π΅Π½: {0}", a*a*a);
