Estimate the joint compound needed to finish drywall.
Joint compound is applied in coats over the taped seams, so total area times coats divided by coverage gives the gallons, and a box equivalent helps compare packaged sizes. Taping and finishing uses several coats, so estimating compound by area prevents running out mid-finish.
