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. Now, another factor on the length of cooking potatoes is how big your potatoes are. Of course, if you use really small potatoes, they will become tender easily.
The fewer potatoes you cook in the microwave at once, the shorter the cooking time. Place up to five or six (depending on the size of your microwave) on paper towels in a spoke pattern and cook for between 6 and 14 minutes, turning them over about halfway through the cooking.
