Calculating Fill Dirt for a Pond Mound: 12×6×3 ft = 8 Cubic Yards

You're building an upper pond mound: 12 ft long × 6 ft wide × 3 ft high. Here's the math.

Volume Calculation

12 × 6 = 72 sq ft (footprint)
72 × 3 = 216 cu ft
216 ÷ 27 = 8 cu yds

Ordering

• 8 cubic yards = half a tandem-axle dump truck load.
• Order "clean fill" or "structural fill"—screened, low organic, compacts well.
• Compact in 6–8″ lifts with a plate compactor or jumping jack.
• Top with 6–12″ of topsoil for planting if needed.

Tell the supplier: "8 yards of screened structural fill, delivered." Confirm truck access.
