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 [tex] \frac{1}{2}*b*h[/tex] where b is the base and h is the height. In this case, the base is 16 and the height is 8.
[tex]A = \frac{1}{2}*16*8[/tex]
[tex]A = \frac{1}{2}*128[/tex]
[tex]A = 64[/tex]
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.
[tex]64 * 22 = 1408 cm^3[/tex]
Therefore, the final answer is 1408 [tex]cm^3[/tex].
