12.5 m³
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Loose volume = in-place volume × (1 + swell/100).
A WORKED EXAMPLE
Using in-place volume = 10 m³, volume increase = 25 %, the result is 12.5 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.
