Activity 1: Properties of a Cube

In this activity, we will use user-defined functions to calculate the properties of a cube — its volume, surface area, and the length of its face diagonal. This is a great example of how functions make code clean and reusable.

Writing the Script

import math # Function to calculate volume def cube_volume(side): return side ** 3 # Function to calculate surface area def cube_surface_area(side): return 6 * side ** 2 # Function to calculate face diagonal def cube_face_diagonal(side): return side * math.sqrt(2) # Main program side = float(input("Enter the side length of the cube: ")) volume = cube_volume(side) surface_area = cube_surface_area(side) diagonal = cube_face_diagonal(side) print("Volume: " + str(volume)) print("Surface Area: " + str(surface_area)) print("Face Diagonal: " + str(round(diagonal, 2)))
