Answer to the first question: New York state wildlife expert Richard Thomas found that a woodchuck could (and does) chuck around 35 cubic feet of dirt in the course of digging a burrow. Thomas reasoned that if a woodchuck could chuck wood, he would chuck an amount equivalent to the weight of the dirt, or 700 pounds.
Answer to the second question: Considering that Peter Piper is also going to be pickling these peppers, which involves soaking them in vinegar, this is a good estimate. There are 16 cups in a gallon, and 32 cups in 2 gallons, so 32 peppers will give you roughly 2 gallons. So there you go, 32 peppers.
Those are my two professional answers... LOL
