Answer 2

Correct option D) 1,185.6 inches cubed .

Explanation:

Here we have , A triangular prism. The triangular base has a base of 12 inches and height of 10.4 inches. The height of the prism is 19 inches. We need to find the volume of the triangular prism .Let's find out:

We have following parameters :

`b=12 inches\\h=10.4inches\\l=19inhes`

We know that , Volume of triangular prism is :

⇒
`Volume = (1)/(2)b(h)(l)`

⇒
`Volume = (1)/(2)12(10.4)(19)`

⇒
`Volume = 6(10.4)(19)`

⇒
`Volume = 1,185.6in^3`

Therefore , Correct option D) 1,185.6 inches cubed .
