  "description": "A 12x24 pool deck is a common surround size for an above-ground or small inground pool. This calculator defaults to a 4-inch concrete slab, returning ready-mix cubic yardage and total cost, so you can plan the deck area before pouring.",
  "formula": "Cubic Yards = (Length × Width × Thickness in inches ÷ 12) ÷ 27 × (1 + Waste%). Cost = Cubic Yards × Price per Yard.",

      "q": "Should a pool deck slope?",
      "a": "Yes, a slight slope (about 1/4 inch per foot) away from the pool is standard to keep water from pooling on the deck surface."

      "q": "Can I use pavers instead of poured concrete?",
      "a": "Yes, pavers are popular around pools because they stay cooler underfoot and individual pieces can be replaced; swap this tool's output for the paver patio calculator if going that route."
