Question

Oh I need is the answer is please thank you

Answer 1

The volume of a triangular pyramid can be calculated through the formula:

`V=A_b\cdot(h)/(3)`

using the area of a triangle we get

`\begin{gathered} V=(b\cdot(a)/(2))\cdot(h)/(3) \\ V=(1)/(6)\cdot b\cdot a\cdot h \end{gathered}`

then, with the information given

`\begin{gathered} V=(1)/(6)\cdot12\cdot8\cdot9.2 \\ V=147.2cm^3 \end{gathered}`
