The base area of triangular pyramid is B = 34.
The height of triangular pyramid is h = 8.
The formula for the volume of triangular pyramid is,
[tex]V=\frac{1}{3}\cdot B\cdot h[/tex]Substitute the values in the formula to obtain the volume of triangular pyramid.
[tex]\begin{gathered} V=\frac{1}{3}\cdot34\cdot8 \\ =\frac{272}{3} \\ =90.6666 \\ \approx90.67 \end{gathered}[/tex]Thus, volume of triangular pyramid is 90.67 inch cube.
