Calculate the volume in cubic feet and the capacity in bushels for a rectangle-shaped grain bin.
V= W*L*H PV= W*L*PH/2 = PV
where V is the volume W the width of the bin L the bin length PH is the peak height PV is the volume of the peak
One US bushel (bu US) = 1.244456 cubic feet (ft³) One Imperial bushel (bu Imperial) = 1.284349 cubic feet (ft³)
