Answer:

Explanation:
You need to use the following formula to calculate the volume of Triangular prism:

Where "a" is the area of one triangular base and "h" is the height of the triangular prism.
Calculate "a" with this formula:

Where "b" is the base of the triangle and "H" is the height.
In this case:

Then, substituting values, you get that the area is the following:

Finally, you must substitute values into the formula for calculate the volume of the triangular prism, and you also must substitute
, which is its height:
