Calculus may not be appropriate here, although that is needed for arbitrary pyramid.

See this, this proof why 1/3*A*h for triangular based pyramid.

You may need to use the links to go into the details if you need, in particular Proposition 5 is probably the most important one to look for.

For arbitrary shaped pyramid, think of they are composed to many small triangular based one :).
