For this case we have that the volume of the rectangular prism is given by:
[tex]V = A_ {b} * h[/tex]
Where:
[tex]A_ {b}:[/tex] It is the area of the base
h: It's the height
We have that the base is a triangle, so, the area of the base is the area of the triangle:
[tex]A_ {b} = \frac {9 * 4} {2} = 18 \ units ^ 2[/tex]
The height of the prism is 18 units.
So, the volume is:
[tex]V = 18 * 18 = 324 \ units ^ 3[/tex]
ANswer:
[tex]324 \ units ^ 3[/tex]
Option C
