Solution:

Given regular pyramids;

The volume, V, of a regular pyramid is;

$\begin{gathered} V=(1)/(3)bh \\ \\ \text{ Where }b=area\text{ of base},h=height \end{gathered}$

(a)

$\begin{gathered} S_(ABCD)=9cm^2,SO=5cm \\ \\ V=(1)/(3)(9)(5)cm^3 \\ \\ V=15cm^3 \end{gathered}$

(b)

$\begin{gathered} S_(ABCDEF)=500mm^2,SO=3cm \\ \\ S_(ABCDEF)=50cm^2 \\ \\ V=(1)/(3)(50)(3)cm^3 \\ \\ V=50cm^3 \end{gathered}$
