What to do with the number
Bulk ordering is usually easier for large beds; bag count is useful for smaller projects and comparing retail prices. If you are refreshing an existing bed rather than starting bare, measure the depth you actually need to add.
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.
