Question

1. Write a C# application that implements a class ‘Prism’ with the following members.
   1. Five private data members ‘length’, ‘height’, ‘width’, ‘Volume’ and ‘Area’ of double data type.
   2. Implement the constructor Prism( ) to accept the length, height, and width of the rectangular prism from the user.
   3. Implement three methods, Vol(), Area(), and Result()
      1. Vol() – to calculate the volume of the prism using the formulae Volume= length ×height ×width
      2. Area() – to calculate the surface area of the prism using the formulae SurfaceArea=2×length×height+2×length×width+2×width×height
      3. Result() – to display the volume and surface area of the prism.

In the Main method, create an object of the above class, and use the object to call the methods to display the output as shown below.

Answer 1

Code:
using System;

class Prism
{
//declaring variales
private double length;   
private double breadth;
private double height;
private double area;
private double volume;
  
//constructor to input length,breadth and width
public Prism()
{
Console.WriteLine("Enter Length of rectangular prism: ");
length = Convert.ToDouble(Console.ReadLine());
  
Console.WriteLine("Enter Height of rectangular prism: ");
height = Convert.ToDouble(Console.ReadLine());
  
Console.WriteLine("Enter breadth of rectangular prism: ");
breadth = Convert.ToDouble(Console.ReadLine());
  
  
}
  
//function to calculate volume
public void Volume()
{
  
volume=length*breadth*height;
}
//function to calculate area
public void Area()
{
area = (2*length*height) + (2*length*breadth) + (2*breadth*height);
}
//function to display voulume and area
public void Result()
{
Console.WriteLine("\nVolume of rectangular prism is: {0}",volume);
Console.WriteLine("Surface area of rectangular prism is: {0}",area);
}
static void Main()
{
//creating object
Prism prism = new Prism();
//calling class functions
prism.Volume();
prism.Area();
prism.Result();

}
}

40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 public void Result() Console.WriteLine("\nVolume of rectangular prism is: {0}", volume); Console.WriteLine("Surface area of rectangular prism is: {0}", area); static void Main() //creating object Prism prism = new Prism(); //calling class functions prism.Volume(); prism.Area(); prism. Result(); } { }


Output:

Enter Length of rectangular prism: 10 Enter Height of rectangular prism: 12 Enter breadth of rectangular prism: 15 Volume of rectangular prism is: 1800 Surface area of rectangular prism is: 900
