To calculate these costs, you must consider these aspects of the manufacturing environment: Product costing (detailed information) for material, labor, and overhead. Cost reporting (what does the item really cost to produce). Variance reporting (actual versus standard costs).
In a pot, heat water until it boils. Once it boils, add in your potatoes. After about 20 minutes, you can try forking in your potatoes to see how tender it is.

When the time is up, use a fork to pierce different areas of the potato.
