Surface Area and Volume of Hexagonal Prism

Given a Base edge and Height of the Hexagonal prism, the task is to find the Surface Area and the Volume of hexagonal Prism. In mathematics, a hexagonal prism is a three-dimensional solid shape which have 8 faces, 18 edges, and 12 vertices. The two faces at either ends are hexagons, and the rest of the faces of the hexagonal prism are rectangular. 

where a is the base length and h is the height of the hexagonal prism.

Surface Area = 
Volume = 

Examples:

Input : a = 4, h = 3
Output : Surface Area: 155.138443
         Volume: 124.707657

Input : a = 5, h = 10
Output : Surface Area: 429.904
         Volume: 649.519
