I am going to assume it is a regular pentagonal prism.

a=12, b=6 and h=8.2
the area of the pentagon base = 5* (1/2)*6*12 = 180 thingys squared
Volume of pentagon = 180*8.2 = 1476 thingys cubed
area of each rectangular side = 6*8.2= 49.2 thingys squared
surface area = $${\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{49.2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{180}} = {\mathtt{606}}$$ thingys squared 
Did I get the terminology correct TitaniumRome ?
