Volume of triangular prism is given by the formula:
[tex]\begin{gathered} V=Area\text{ of cross-section }\times length \\ V=\frac{1}{2}\times base\times height\times length \end{gathered}[/tex]
Thus, we have:
[tex]\begin{gathered} V=\frac{1}{2}\times8\times7\times25 \\ V=\frac{1400}{2} \\ V=700\text{ cubic inches} \end{gathered}[/tex]
Hence, the volume of the triangular prism is 700 cubic inches
