Answer:

495 in

Step-by-step explanation:

The formula for the volume of a triangular prism is V = $\frac{1}{2}$ · w · h · l, where w represents with, l represents length, and h represents height. Using this and plugging in the values, we can solve.

V = $\frac{1}{2}$ · 5 · 11 · 18

V = 2.5 · 11 · 18

V = 27.5 · 18

V = 495

hope this helps :)
