The method, explained

Mulch volume = length × width × depth in cm/100.

A WORKED EXAMPLE

Using length = 5 m, width = 4 m, mulch depth = 5 cm, the result is 1 m³. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.
