Answer:

The Volume of the pyramid is;


186.1\text{ }m^3

Step-by-step explanation:

Given the pyramid with a square base and dimensions;


\begin{gathered} l=10.9m \\ h=\text{4}.7m \end{gathered}

Recall that the volume of a pyramid can be calculated using the formula;


V=(l* l* h)/(3)

Substituting the given values;


\begin{gathered} V=(10.9*10.9*4.7)/(3) \\ V=186.1m^3 \end{gathered}

Therefore, the Volume of the pyramid is;


186.1\text{ }m^3
