To find the volume of a triangular pyramid, the formula is:


V=(1)/(3)(Area\text{ }of\text{ }thebase)(height)

So we start by finding the area of the base, which is in the shape of a right triangle in this case.

The area of a right triangle is equal to 1/2 x base x height.


\begin{gathered} A=(1)/(2)bh \\ \\ A=(1)/(2)(5)(6) \\ \\ A=15\text{ square feet} \end{gathered}

We use this area to find the volume.


\begin{gathered} V=(1)/(3)Ah \\ \\ V=(1)/(3)(15)(6) \\ \\ V=30\text{ cubic feet} \end{gathered}

The volume of the triangular pyramid is 30 cubic feet.
