Find the volume of the given right prism. Look at photo for accurate description

From the diagram given, we have a right prism labelled as follows;
[tex]\begin{gathered} Side\text{ lengths}=9 \\ \text{Height}=17 \end{gathered}[/tex]The volume is calculated by multiplying the area of the triangle by the height.
The area of the triangle given two sides is;
[tex]\begin{gathered} \text{Area of a triangle}=\frac{1}{2}bh \\ b=9,h=9 \\ \text{Area}=\frac{1}{2}\times9\times9 \\ \text{Area}=\frac{81}{2} \\ \text{Area}=40.5units^2 \end{gathered}[/tex]Therefore, the volume of the right prism is;
[tex]\begin{gathered} \text{Volume}=\text{Ah} \\ \text{Where,} \\ A=\text{area of triangle} \\ h=\text{height of prism} \\ \text{Volume}=40.5\times17 \\ \text{Volume}=688.5units^3 \end{gathered}[/tex]ANSWER:
The volume of the right prism is 688.5 units cubed
