ANSWER
66 cubic units
EXPLANATION
The volume of a triangular prism is the area of the triangular base times the height of the prism.
We calculate the volume using the formula:
[tex]volume = \frac{1}{2} bh \times H[/tex]
where b=4 is the base of the triangle and h=3 is the height of the triangle.
H=11 is the height of the prism.
We substitute these values to get;
[tex]volume = \frac{1}{2} \times 4 \times 3 \times 11[/tex]
[tex]volume = 66 \: cubic \: \: units[/tex]
