Answer:
234 cubic units
Step-by-step explanation:
The first thing that you need to do is to find the volume of the triangular base. The formula for the area of a triangle is [tex]\frac{bh}{2}=\frac{18\cdot9}{2}=81[/tex]. Multiplying this by the height of 13 you get 18*13=234 cubic units. Hope this helps!
