Date: 26/10/2023

AIM:

To design a website to find total surface area of a square prism in server side.

FORMULA:

DESIGN STEPS:

Step 1:

Clone the repository from GitHub.

Step 2:

Create Django Admin project.

Step 3:

Create a New App under the Django Admin project.

Step 4:

Create python programs for views and urls to perform server side processing.

Step 5:

Create a HTML file to implement form based input and output.

Step 6:

Publish the website in the given URL.
