The length of rectangular pyramid is l = 5 feet.

The width of rectangular pyramid is w = 4 feet.

The height of rectangular pyramid is h = 9 feet.

The formula for the volume of rectangular pyramid is,

$V=(l\cdot w\cdot h)/(3)$

Since there are two rectangular pyramid so net volume of figure is,

$V^(\prime)=(2)/(3)\cdot l\cdot w\cdot h$

Substitute the values in the formula to obtain the volume of figure.

$\begin{gathered} V^(\prime)=(2)/(3)\cdot5\cdot4\cdot9 \\ =10\cdot4\cdot3 \\ =120 \end{gathered}$

So volume of figure is 120 feet cube.
