Given a figure of a triangular pyramid.

the volume of the triangular pyramid = 1/3 * B * h

Where B is the area of the base and (h) is the height

So, h = x

and B = 1/2 * 10 * 6 = 30

the volume of the triangular pyramid = 90 units³

So, we can write the following equation:


\begin{gathered} (1)/(3)*30*x=90 \\ 30x=3*90 \\ 30x=270 \\ x=(270)/(30)=9 \end{gathered}

So, the answer will be x = 9
