The volume of the triangular prism is given by
[tex]V=\frac{1}{2}b\cdot h\cdot l[/tex]
where,
By substituting the values into the volume formula, we get
[tex]\begin{gathered} V=\frac{1}{2}(5)\cdot(10)(12) \\ V=\frac{1}{2}\cdot600 \\ V=300 \end{gathered}[/tex]
that is, the volume is equal to
[tex]V=300in^3[/tex]
