Estimate soil mix volume and bags to fill a raised bed.
A raised bed's soil volume is its footprint times the fill depth. Bulk soil is sold by the cubic yard while small bags are sold per bag, so both figures help ordering. Buying the right volume avoids expensive surplus and prevents a bed from settling below a workable depth within the first season.
Raised Bed Soil
Volume = length x width x depth; yards = feet ÷ 27
