Explanation:
Find the diagram attached.
The volume of a triangular prism =
![(base\ area *height)/(3)](https://img.qammunity.org/2021/formulas/mathematics/college/j6boohsxuwm0kd1eycxyw6g5216xfk7xcm.png)
Since the base is a triangle, Base area = 1/2 * base * height
given base of the triangular base = 8in
height of the triangle = 9in
Base area = 1/2 * 8 * 9
Base area = 4*9
Base area = 36in²
Height of the prism = 10in
Volume of the prism =
![(36*10)/(3)](https://img.qammunity.org/2021/formulas/mathematics/college/6bf2myk6x3sk2vak77gt0bzc6ua7pc35zm.png)
Volume of the prism =
