I would use 25 pounds of potato
The answer will vary with the size of the potato. 4 to 5 medium potatoes would equal about 1 pound. One medium potato is equal to about 1/2 cup, so one pound of potatoes would be equal to about 2 cups of mashe potatoes.
One pound of of white or russet potatoes makes approximately 1 3/4 cups of mashed potatoes. Using that measurement, then five pounds of potatoes would make approximately 8 3/4 cups of mashed potatoes. Source: http://southernfood.about.com/library/info/blequivp.htm
