It's 4. The factors of 12 are: 1,2,3,4,6,12. The factors of 20 are: 1,2,4,5,10,20.
Since Density = mass/ volume (d = m / v), and assuming the 15 fish weigh 1 gram each - if weight of each fish isn't given - (making that a total of 15 grams),
D = m / v
0.3 = 15 / v
v = 15 / 0.3 = 50 ft cubed
Hope this answers your question correctly :)
