What to do with the number
This covers material volume only. Reinforcing steel, excavation, code requirements and soil conditions are separate design questions. Measure the formed dimensions rather than the nominal lumber dimensions used to create the form.
Planning estimate
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
