Answer:
The volume is 1120 units³.
Step-by-step explanation:
The volume of a prism is the multiplication of the cross sectional area by its length.
Therefore, find the area of the triangle, and then multiply it by the length:
[tex]v = ( \frac{8 \times 14}{2} )(20) = \\ = (4 \times 14)(20) = \\ = 56(20) = \\ = 1120[/tex]
