Worked out by ShedBuilder from the measured size and today's prices. Slab and concrete figures cover the footprint only; add a margin if you want a path around it.
A 20 x 10 ft shed needs a firm, level base at least 20 x 10 ft. Most guarantees depend on it. A concrete slab or paving lasts longest. A plastic grid filled with gravel is quicker, drains well and needs no concrete.

Even pressure-treated buildings last longer with a coat of treatment every couple of years. Do the first coat before it goes up, while you can reach every board edge.
