Calculating area volume from longitude, latitude and altitude

Hello! I'm trying to calculate the volume of airspace(3d polygon) from its longitude, latitude and altitude.
The polygon's vertices are given with longitude and latitude (ex. [128 129 129 128 128], [37 37 38 38 37])
and its altitude ranging from 1000~5000 feet.
How can I get the volume of this 3d polygon?
