Answer 3

the formula for the volume of a pyramid is v=lw (h/3)

Answer 4

the requested volume, is given by the subsequent formula:
\[\huge volume = \frac{{base\;area \times height}}{3}\]

Answer 5

and the base area is given by the subsequent formula:
\[\huge \begin{gathered}
base\;area = \frac{{perimeter \times apothem}}{2} = \hfill \\
\hfill \\
= \frac{{\left( {11 \times 5} \right) \times 7.6}}{2} = ...? \hfill \\
\end{gathered} \]

Answer 6

209

Answer 7

correct!

Answer 8

so, the requested volume is:
\[\huge \begin{gathered}
volume = \frac{{base\;area \times height}}{3} = \hfill \\
\hfill \\
= \frac{{209 \times 12}}{3} = ...? \hfill \\
\end{gathered} \]

Answer 9

836

Answer 10

that's right!
