Question

Calculate the volume of a regular pyramid if the area of the base and the altitude lenght are given.

Answer 1

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)
