Volume of Rectangular Prism in F#

Introduction

In this article I have explained prisms and how to compute the volume of a rectangular prism in a Windows Forms application.

Prism

A prism has flat sides and the same cross-section along its length. A cross-section is the shape you get when cutting straight across an object.

Volume of a Rectangular Prism

To calculate the volume of a rectangular prism you need to know its height, width and length. To determine the volume of a rectangular prism, just use the following procedure:

• Find the length of the rectangular prism: The longest side of the flat surface of the rectangle on the top or bottom of the rectangle prism.
• Find the width of rectangular prism: Width is the shorter side of the flat surface of the rectangle on the top or bottom of the rectangle prism.
• Find the height of rectangle prism: Height is the part of the rectangular prism that rises up and stretches up a flat rectangle until it becomes a three-dimensional shape.
• Volume of the Prism: After determining the height, width and length, multiply them in any order to get the same output. The formula for determining the volume of a rectanglar prism is:
  volume = height * width * length
• State your answer in cubic units: The volume unit is in cubit units because you are working in three-dimensional space. For example: 20 will be 20 in3.

Now  I want to show you how to compute the volume of a rectangular prism in a Windows Forms application. Let's use the following procedure.

Step 1:

Open Visual Studio then select "Create New Project" --> "F# Console Application".

Step 2:

Now go to the Solution Explorer on the right side of the application. Right-click on "References" and select "Add references".

Step 3:

After selecting "Add References", in the framework template you need to select "System.Windows.Forms" and "System.Drawing" while holding down the Ctrl key and click on "Ok".

Step 4:

Provide the following code in  the F# editor:

open System  

open System.Windows.Forms  

open System.ComponentModel  

open System.Drawing   

let RecPrismForm=new Form(Text="Rectangular prism volume")  

RecPrismForm.BackColor<-Color.Bisque

//enter the length value

let lengthlbl=new Label(Top=10,Left=0,Width=130)

lengthlbl.Text<-"Enter Length value:"  

let lenghttxtbox=new TextBox(Top=10,Left=140,Width=80)  

//enter the width value

let widthlbl=new Label(Top=40,Left=0,Width=130)  

widthlbl.Text<-"Enter Width value:"

let widthtxtbox=new TextBox(Top=40,Left=140,Width=80)  

//enter the height value

let heightlbl=new Label(Top=70,Left=0,Width=130)

heightlbl.Text<-"Enter Height Value:"  

let heighttxtbox=new TextBox(Top=70,Left=140,Width=80)  

//after compute prism volume displayed here

let pvolumelbl=new Label(Top=120,Left=80,Width=80)  

pvolumelbl.Text<-"Prism Volume:"

let prismvolumelabel=new Label(Top=120,Left=180,BorderStyle=BorderStyle.FixedSingle)  

//create buttons

let manipulatebtn=new Button(Top=180,Left=120,Width=80)

manipulatebtn.BackColor<-Color.Ivory

manipulatebtn.Text<-"Compute"  

let exitbutton=new Button(Top=180,Left=220,Width=80)

exitbutton.BackColor<-Color.Ivory

exitbutton.Text<-"Exit"   

//adding the controls in form

RecPrismForm.Controls.Add(lengthlbl)  

RecPrismForm.Controls.Add(lenghttxtbox)  

RecPrismForm.Controls.Add(widthlbl)  

RecPrismForm.Controls.Add(widthtxtbox)  

RecPrismForm.Controls.Add(heightlbl)  

RecPrismForm.Controls.Add(heighttxtbox)  

RecPrismForm.Controls.Add(pvolumelbl)  

RecPrismForm.Controls.Add(prismvolumelabel)  

RecPrismForm.Controls.Add(manipulatebtn)  

RecPrismForm.Controls.Add(exitbutton)  

//Manipulate the prism valume

manipulatebtn.Click.Add(fun compute->  

let lenghtvalue=Convert.ToDouble(lenghttxtbox.Text)  

let widthvalue=Convert.ToDouble(widthtxtbox.Text)  

let heightvalue=Convert.ToDouble(heighttxtbox.Text)  

let prismvol=lenghtvalue*widthvalue*heightvalue  

prismvolumelabel.Text<-Convert.ToString(prismvol))           

exitbutton.Click.Add(fun exit -> RecPrismForm.Close())    

Application.Run(RecPrismForm)  

 

Step 5:

Debug the application by pressing F5 to execute the Windows Forms application. After debugging the application the output will be as shown in the following figure:

Step 6:

Enter the Length value.

 

Step 7 :

Enter the Width value.

Step 8:

Enter the Height value.

Step 9:

Compute the rectangular prism value; just click the "Compute" button.

Summary

In this article we explained how to determine the volume of rectangular prism in a Windows Forms application.
