I have no idea. I have aggregated some of the ground screw calculators to get to that number. Shed will likely be 18' x 12' and a lot of timber. Maybe.
Edit: ground screws on 3ft centres would mean 35 screws. Not sure how you calculate for piers, especially if suspended off threaded bar on top as suggested.
