Convert a landscaping area and depth into cubic yards, bags or tonnes.
Volume is a simple product of area and depth, but the mass varies fourfold across these materials, which is what determines whether a vehicle can carry the load. Bags are far more expensive per cubic metre than bulk delivery. The crossover from bags to bulk delivery is usually around one cubic metre, and the coverage line shows how quickly depth consumes material.

Volume = area × depth; mass = volume × material density
