--- Christmas Wrapping Challenge ---

The elves in the workshop are in a wrapping frenzy! Every day, they receive boxes of presents that need to be wrapped before Santa's big night. However, there’s a twist: the elves only have a limited number of wrapping materials, and they want to minimize waste.

The wrapping requirements are simple:

  • Each present comes in a box with dimensions: length, width, and height.
  • To wrap a box, you need enough material to cover all six sides plus a little extra for the smallest side as a spare.

The list of presents which need to be wrapped can be generated in your terminal using the following command:

python challenge_1.py

For example, if a box has dimensions 2x3x4:

  • The surface area of the box is 2 × (2 × 3 + 3 × 4 + 4 × 2) = 52.
  • The smallest side of the box is 2 × 3 = 6, so you need an additional 6 units of wrapping material.
  • The total material needed is 52 + 6 = 58.

Your task is to calculate how much total wrapping material is needed for all the boxes on the elves’ list.

Input:

The elves will provide you with a list of box dimensions in the following format:

2x3x4
1x1x10

Each line represents the dimensions of a single box: length x width x height.

Output:

Write a program that:

  1. Reads a list of dimensions.
  2. Calculates the total wrapping material needed for all the boxes.
  3. Prints the total.

Example:

Given the input:

2x3x4
1x1x10

Your program should output:

Total wrapping material needed: 101

Challenge:

Can you modify your program to also calculate the ribbon needed for each box? For ribbon:

  • You need enough to wrap around the smallest perimeter of the box.
  • You also need a bow, which uses material equal to the volume of the box.

For example, for a box with dimensions 2x3x4:

  • The smallest perimeter is 2 × (2 + 3) = 10.
  • The volume of the box is 2 × 3 × 4 = 24.
  • The total ribbon needed is 10 + 24 = 34.

If you’re up for it, modify your program to calculate both wrapping material and ribbon needed! Good luck!

Expected Output:

"The total wrapping paper needed is: {calculated wrapping paper total}"

"The total ribbon needed is: {calculated ribbon total}"
