How long does it take for 10 lbs of potatoes to boil?

It depends on the size of the potatoes and the amount of water used. Generally speaking, it takes around 15-20 minutes to boil 1 lb of potatoes, so for 10 lbs it should take around 2-2.5 hours. However, it is recommended that you check the potatoes periodically with a fork or knife to see if they are done. Once they are tender all the way through, they are done.
