Check the picture below.

as you can see, we have 6 rectangles, so let's get the area of each and sum them up and that's the area of the prism.


\stackrel{\textit{\large Areas}}{\stackrel{\textit{left and right}}{2(6\cdot 5)}+\stackrel{\textit{front and back}}{2(4\cdot 6)}+\stackrel{\textit{top and bottom}}{2(4\cdot 5)}}\implies 60+48+40\implies 148
