The volume V of a pyramid is given by;
[tex]V=\frac{l\times w\times h}{3}[/tex]
Where the dimensions are;
[tex]\begin{gathered} \text{length l=18cm} \\ \text{width w=15cm} \\ \text{height h=25cm} \end{gathered}[/tex]
Thus, the volume of the pyramid is;
[tex]\begin{gathered} V=\frac{18\times15\times25}{3} \\ V=2250\operatorname{cm}^3 \end{gathered}[/tex]
