Given:-


  • \rm{Base ( B ) = \bold{75m²}}


\:


  • \rm{Height ( H ) = \bold{7.4m}}


\:

To find:-


  • \textrm{Volume of pentagonal pyramid = ?}


\:

By using formula:-


\color{gray}{ \bigstar} \blue {\boxed{ \rm{ \green{Volume \: of \: Pyramid = (1)/(3) Bh}}}}


\:

Solution:-


\rm{Volume \: of \: Pyramid = (1)/(3) Bh} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\rm \: = (1)/(3) * 75 * 7.4 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \rm = \frac{1} {\cancel{3} }* \cancel{555 } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \underline\color{darkgreen}\boxed{ \rm{ = 185}}
