BEHIND THE NUMBERS

Clear math. Better decisions.

Volume = area × depth × allowance factor. Weight = volume × bulk density. Bags = weight ÷ bag weight, rounded up. Compare alternatives; do not add their prices together.

A worked example

At 200 sq ft, 3 inches deep, and 10% extra: 2.04 cu yd. At an entered 100 lb/cu ft: 2.75 US short tons, or 110 × 50 lb bags.

Before you order

  • Compare a rock quote by volume, weight, or whole bags, including the same entered delivery fee for each option.
  • The common starting density is only an arithmetic illustration; rock types can differ substantially.
  • These tools share a volume formula. Compaction, slope, drainage performance, and minimum delivery increments need supplier confirmation.

Good questions.

Where do the prices come from?

You enter actual supplier prices. A blank price is unknown; enter zero only when that item is free or deliberately excluded. Taxes and installation are excluded unless a field explicitly includes them.

Can I use metric measurements?

Yes. The unit selector converts dimensions and unit prices. Results use whole packages where applicable. Starting dimensions are examples; confirm product specifications before ordering.
