How many jars of alphabetic pasta will it take to rewrite The Lord of the Rings with them

The time has come for really important and large-scale research. The programmer decided to find out how many cans of alphabetic pasta it would take to rewrite the entire Lord of the Rings trilogy with them. As we know, Tolkien's work is very large and this whole idea is impossible. However, this guy is a serious person. He clearly calculated everything, including the cost of all the pasta, how many letters will be needed and how many will remain unnecessary.
