Answer:

See below ....none of your answer choices 'fit'

Step-by-step explanation:

Break it into two pieces....a triangular prism and a square pyramid

prism volume = (area) * length

( 1/2 base * height) * length

Use pythagorean theorem to find height of triangular prism = 12

1/2 * 12 * 9 * 21 = 1134 km^3

Pyramid volume = 1/3 base * height =

= 1/3 * (9*21) * 7 = 441 km^3

Summed = <u>1575 km ^3 </u>

olya-2409 [2.1K]

Answer:

2,850

Step-by-step explanation:

4.25 x 9 = 38.25

4.25 x 13 = 55.25

4.25 x 12 = 51

13.70 x 92 = 1260.4

3.28 x 130 = 426.4

8.06 x 126 = 1015.56

all totals would equal 2,846.86, which to the nearest would be $2,850
