Volume = mass / specific gravity. Units are cubic centimeters and grams or cubic meters and tonnes. s.g. has no units : it is a dimensionless quantity.
This question cannot be answered sensibly. A cubic foot is a measure of volume, with dimensions [L3]. A pound is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that in most cases you cannot convert between measures with different dimensions without additional information. It takes only a little mental effort to compare a cubic foot of air and a cubic foot of lead and come to the conclusion that the two will have very different masses.
If these measurements are made in cubic cemtimeters (volume) and grams (mass) this is true. But, if mass is from the english system, (not really pounds, it is slugs, but who knows what a slug is?) and the volume is cubic feet, this is not true.

The density of soil varies widely depending upon how much moisture it contains and how loosely packed it is. A cubic foot of packed earth weighs about 95 pounds per cubic foot; moist earth weighs about 90 pounds per cubic foot; and excavated loam weighs about 78 pounds per cubic foot. One ton (an American or "short ton") of moist earth, therefore, occupies about 22.2 cubic feet (2000 pounds per ton divided by 90 pounds per cubic foot). That is equal to about 0.629 cubic meters. (One cubic meter is equal to about 35.3 cubic feet.)
A object weighing 10 pounds with a volume of 1 cubic foot will sink until 0.16 of its volume is under water, and the remaining 0.84 of its volume is above the surface. At that point, the weight of the displaced water is (0.16 cubic foot) x (62.5 pounds/cubic foot) = 10 pounds, and the object will float at that depth, and sink no further.
Specific weight is the weight of the material per unit volume. Water has the specific weight of 62.43 pounds per cubic foot or 9.807 Newtons per cubic meter.
Volume = 10 ft3 (given) Density = 0.4 pounds per ft3 Specific gravity = about 0.0064 (using 62.5 pounds per ft3 for water)

density is the inverse of specific volume; in this case 1/.001865 = 536.2 pounds per cubic foot
Pounds is an obsolete unit for mass, cubic foot is a unit of volume !
A measurement of 179 cubic inches has no direct equivalent in pounds. Cubic inches measure volume while pounds measure weight.
A measurement of 179 cubic inches has no direct equivalent in pounds. Cubic inches measure volume while pounds measure weight.
Pounds can't be converted to cubic feet. Pounds measure mass, while cubic feet measure volume.
Cubic feet can't be converted to pounds. Cubic feet measure volume, while pounds measure mass.
It is impossible to answer the question because there are no units given. It makes a huge difference whether the mass is in pounds or grams (or kilograms) and the volume is in cubic inches or cubic centimetres (or cubic metres).It is impossible to answer the question because there are no units given.

0.4 pounds per cubic feet - a very massive gas!
