A bungee cord is stretched twice its length. what changed? volume? mass? density?

No change in density, mass or volume...(in ideal case scenario if the chord does not suffer any damages due to external forces)
consider bungee chord as a sectional cylinder. when u stretch, length (h) increases and diameter (2r) reduces through necking process.
Volume=pi*r^2*h = mass/density
Density of material of bungee chord is constant ( X kg/m^3)
If volume and density is constant, mass is constant...

Density

density=mass/volume
i believe when a bungee cord stretches, its length gets longer but its width gets thinner....so the volume wouldnt change. however, the mass dfefinetely does NOT change. if volume does change, then density will also, but mass will NOT.

If density changes, either mass or volume must change. It's density and volume.

V=Mass/Density 30 grams/1.1639 g/cm^3 The answer should be __ cm^3

I think that it would be the volume beacuse the volume of a solid body is the amount of "space" it occupies.

None of the above. Think about a coiled spring.
