Sod Area & Cost Calculation for a 640-Yard Perimeter Square

A square with 640-yard perimeter = 160 yards per side = 25,600 sq yd = 230,400 sq ft. At 2-inch sod depth:

• Volume: 230,400 sq ft × 0.167 ft = 38,477 cu ft (not 55,296).
• At $0.40/sq ft: 230,400 × $0.40 = $92,160 (not $22,118).

Note: Original answer had math errors. Always verify calculations before ordering.

Practical Steps

1. Measure actual area (satellite view + wheel measure).
2. Order 5–10% extra for waste.
3. Prep: kill existing vegetation, till 4–6″, amend, level, roll.
4. Lay sod green-side-up, stagger seams, roll, water immediately.

For large areas, hire a sod installer—equipment and labor justify the cost.
