Answer:
The answer should be B. 600m³
Step-by-step explanation:
Because the height needs to be perpendicular, so the 5m measurement should be the height, 13m doesn't matter. Now we just multiply every things, 12 x 5 x 20 is 1,200, and I divide it by 2, making it 600.
Answer:-126f-108
9(-9f - 2)-9(5f +10)
-81f - 18 -9(5f + 10)
- 81f - 18 - 45f -90
- 126f - 18 - 90
-126f -108
which give you the answer -126f - 108
