The volume of any straight prism is the area of the shape base multiplied by the length. In this case, our shape is a triangle and the area of a triangle is
![(1)/(2)*b*h](https://img.qammunity.org/2019/formulas/mathematics/middle-school/rsekpbqia6d0k8cwh8bxpcud6iayddvwh6.png)
where b is the base and h is the height. In this case, the base is 16 and the height is 8.
![A = (1)/(2)*16*8](https://img.qammunity.org/2019/formulas/mathematics/middle-school/158pvouga95c8g2i5xilch4adu8gxcrz07.png)
![A = (1)/(2)*128](https://img.qammunity.org/2019/formulas/mathematics/middle-school/xubnkpqecomg5dbfhucji4n31rsjrm0nzy.png)
![A = 64](https://img.qammunity.org/2019/formulas/mathematics/middle-school/hq7kg9weyv262vrm5m5ag0akdzgxkuzhy0.png)
So, now we know the area of the shape is 64. We need only multiply this by the length of the prism, in this case 22.
![64 * 22 = 1408 cm^3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/tmw2kg60zonv5pxv10wunw4ro5wbc27o4g.png)
Therefore, the final answer is 1408
