- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic yards: 48.0 × 0.250 ÷ 27 = 0.44 yd³.
- Tons: × about 1.35 tons per yard = 0.6 tons.

Dog Run tips
For a dog run, rounded stone such as pea gravel is gentle on paws and drains fast. Lay it about 3 inches deep over fabric and edge the run so the stone stays put.

Prep
Remove sod and roots, level the area and slope it slightly for drainage. Install edging so the stone stays inside the footprint.
Buying the stone
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Decomposed granite packs into a firm, natural path when wetted and compacted in thin lifts. Round up by about 10 percent for compaction and uneven ground.
Planning the cost
Quarries and landscape suppliers set their own prices, and they change by region and season. Get the price per ton, the delivery fee and the minimum order. If two products will both work, compare cost per square foot at your depth rather than cost per ton.
Measuring the area
Measure length and width in feet at a few points and use the largest figures, since real sites are rarely square. For odd shapes, split the area into rectangles and circles, work out each one and add them together. Depth is the number most people underestimate: drive a stake, run a level string and measure down to the dug-out surface in several spots.
