growing commercially? 6 qubic meters per 1000 sqm

What is a Qubic litre? A litre is a measure of volume - with dimensions [L3]. A cubic litre (if that is what it is meant to be) would then be a "volume" measure in 9-dimensional space!

There are 27 cubic feet in a cubic yard.
You can't compare square feet with cubic meters because they're two different types of units. Square feet measure area while cubic meters measure volume.
Square feet have dimensions L2 while cubic feet have dimensions L3 so they are not interchangeable.
(22*6)/2 =66 qubic ft
Diameter is a length measurement. Cubic inches is a volume measurement. Diameter cannot be measured in or converted to cubic inches.
