Let a, b, c be the lengths of sides of the base and h be the height of the prism.

Total surface area

\(2\left(\sqrt{\dfrac{a+b+c}{2}\left(\dfrac{b+c-a}{2}\right)\left(\dfrac{a-b+c}{2}\right)\left(\dfrac{a+b-c}{2}\right)}\right)+h(a+b+c)\)

Sorry for being too scary, but that formula is real XDDDD

Simpler version: 

Total surface area

\(2(\text{base area})+h\times(\text{perimeter})\)
