None, since there can be no conversion. A cubit = 1.5 feet so a cubit foot is a measure of area in 2-dimensional space whereas a cubic decimetre is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

There are 3 cubit feet in 1 cubit yard. Although irrelevant in this context, you may wish to know that 1 cubit = 1.5 feet = 0.5 yards.
10 decimeters is about 3.2808399 feet.
67.2 decimeters = 22 feet
1 cubit = 1.5 feet
Many.
2.25 decimeters
1 foot is about 3.048 decimeters.
512 feet squared
Six feet is about 18.288 decimeters.
3 feet is 9.14 decimeters.
Cubic decimetres/decimeters are exactly the same as a Litre/Liter.1 cubic decimetre is the SI unit for volume rather than Litre.2 dm3 = 2 L
