  "summary": "Floor, wall, and roof material estimates for a 10x12 storage shed.",
  "description": "10x12 is one of the most common backyard shed sizes, big enough for a riding mower and tools but still small enough to build in a weekend. This calculator estimates floor decking area, wall siding area based on your wall height, and roof area with pitch, plus a rough total material cost so you can plan your shed build budget.",
  "formula": "Floor Area = Length × Width. Wall Area = Perimeter × Wall Height. Roof Area = Length × Width × Pitch Factor. Cost = (Floor + Wall + Roof Area) × Price per Sq Ft.",
