None, to work out cubic feet you need three dimensions, 3 feet x 20 feet is 60 square feet, to get to cubic feet you need another dimension.
20 x 20 x 3/12 = 100 cu ft at 100 lb/cu ft = 100 x 100 = 10000 pounds = 5 tons
Volume is 30 x 20 x 1/6 ie 100 cu ft. 27 cu ft make one cu yd so 100/27 ie 3.7 cu yds to one significant figure.
One is an area and the other is a volume, so there is no answer.
36-ft x 24-ft x 20-ft = 17,280 cubic feet
depends on how deep you want the nuggets. at 2" (or .17ft) thick: 12 x 16 = 192 sq ft area 192 sq ft x .17ft thick = 32.64 cu ft 32.64 cu ft / 2 cu ft = about 17 bags.
20 x 20 x 3/12 = 100 cu ft at 100 lb/cu ft = 100 x 100 = 10000 pounds = 5 tons
10.5 cu ft

The answer is specific to the product in the cu ft. A cu ft of water will be different than that of a cu ft of feathers ETC.

You cannot convert sq. ft. into cu. ft. because, sq. ft. is the unit of area and the unit of volume. But if you know the cross sectional area of a cylinder in cu. ft. and its length (or height ) in ft. Then you can find its volume in cu. ft. by multiplying cross sectional area and the ;length (or height).
2080 cu ft
1 cu. ft. = 28.32 liters
These are incompatible measurements, as one measures area and the other measures volume. Sorry!
You can't do that. Cu Ft is volume and Ft is length - the units are not the same.
