Solution

The figure is a rectangular based pyramid


Volume,\text{ V of a pyramid =}(1)/(3)\text{ x base area x height}

The height of the pyramid = 7.9in

Area of the rectangular base = Length x breadth = 4.3in x 2in = 8.6in^2


\begin{gathered} Volume,\text{ V of the pyramid =}(1)/(3)\text{ x 8.6 x 7.9 = 22.647in}^3 \\ =22.65in^3(to\text{ 2 decimal places\rparen} \end{gathered}

The second option is the closest to the answer, thus, the correct option
