Walkway gravel
20 ft x 12 ft x 3 in of standard gravel
A typical path or pad project where cubic yards and tons are both helpful for ordering.
Result: A small-to-mid project that usually lands around a couple of tons with waste included
Pea gravel play area
18 ft x 18 ft x 4 in
A softer-surface project where the lower density slightly changes the tonnage.
Result: The bag-count view helps sanity-check whether a pallet of bags is even realistic
Decomposed granite patio
24 ft x 16 ft x 2.5 in
Useful for estimating compacted-surface material before calling a yard.
Result: The lower density changes the ton total but the yardage still stays easy to visualize
