Whatthe answer need help!ASAP.Thank you.

Answer 1

Length x width x height.  Plug in the numbers, the bottom one, the length is 5, width is 3, height is 9.  5 x 3 = 15. 15 x 9 = 135.  Now considering you still have the top one to do, we can eliminate A, B, and C as answer choices.  But if you want proof to solve it, the top figure is length 8 x width 3 x height 3.  8 x 3 = 24. 24 x 3 = 72.  135 + 72 = 207.  Recap:

Bottom Figure:

5 x 3 x 9
5 x 3 = 15, 15 x 9 = 135

Top Figure: 

8 x 3 x 3
8 x 3 = 24, 24 x 3 = 72

135 + 72 = 207.  There is your answer, good luck!

Answer 2

Figure on top is 8 times 9 (to find volume)
the figure on top has a volume of 72 cm^3

the volume of the lower figure:
3 times 9 times 5 = 135 cm^3
72+135=207 cm^3

the volume of both figures is 207 cm^3
