you calculate the area of one side, then multiply it by three.

The triangular prism has the two triangular bases and rectangular side faces.
Assuming you mean a rectangular prism, you get the smallest surface area if the prism is a cube. You can calculate the required length of side to get that volume; then, based on that, the corresponding surface area.
Rectangular Prism surface area formula is Area = 2 (wh + lw + lh) (Length x width of a side) x 2 + (length x width of perpendicular side) x 2 + (length x width of end) x 2 = surface area of a rectangular prism
