I'm am pretty sure that the answer is 320. Hope this helps!
Answer:
DE = 7.07 RS = 11.04 not congruent
Step-by-step explanation:
Formula:

D (5,0) E (0,-5)
DE




d= 7.07
R (-5,-5) S (6,-6)
RS




d= 11.04
V = S^3
S= 1/3
V = 1/3^3
V = 1/27 cubic unites each
3 cubes = 1/27 x 3 = 3/27 = 1/9 cubic units total
That would be "c" because you would have to subtract 85 from 120 and then your answer is less then 85
