$2\mathrm{.}4\mathrm{.}1$: Method definition: Volume of a pyramid with modular methods.

Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns

as a double the volume of a pyramid with a rectangular base. calcPyramidVolume$()$ calls the given calcBaseArea$()$ method in the

calculation.

Relevant geometry equations:

Volume $=$ base area $$ height $\frac{1}{3}$

Base area $=$ base length $x$ base width.
