The area of the triangle is 3 * 4 = 12.
Therefore, the volume would be 12 * 12, which is 144.
we have given a triangluar prism and it dimensions.
formula for traingular prism is [tex] V=base area of triangle *height [/tex]
[tex] V=1/2*b*h_{t} *h [/tex]
[tex] V=\frac{1}{2} *8*3*12=144,units^3 [/tex]
so option D is the answer.
