Calculate and Account for Waste

What happens here

The final instruction provided is to "Multiply numbers, add for waste." This refers to calculating the total surface area of the walls by multiplying the total perimeter measurement by the height measurement. Once the theoretical area is determined, it is crucial to add an additional percentage (e.g., 10-15%) for waste when purchasing materials. This waste factor accounts for cuts, mistakes, patterns, and any unforeseen issues during installation.

Goal: Accurately estimate required material quantities, including a waste factor
