Answer :
[tex]Volume=the\ base\ area\ multiplied\ by\ the\ height\\\\if\ the\ base\ is\ a\ rhombus,\ \ then\ the\ base\ area= \frac{1}{2}\cdot e\cdot f \ \ \\\\and\ \ \ e,f\rightarrow\ the\ length\ of\ the diagonals\ of\ a\ rhombus\\\\V=\frac{1}{2}\cdot e\cdot f \cdot h\\\\and\ \ h\rightarrow\ the\ height\ of\ prism[/tex]
