This takes a bit of math. If there are lots of sides, figure 1/2 cup per serving; higher if your're feeding teenage boys! Using a generous 1/2 cup figure (generous for rounding off), then you need 125 cups. Two cups to a pint, 64 pints. Two pints to a quart, 32 quarts. Four quarts to a gallon, eight gallons.
4 1/2 gallons per 100 is the max (about 6 pounds dry pasta per 100); -Ellen add a comment
