ANSWER:

The surface area of the figure is 574 in^2

Explanation:

We have that the surface area of a rectangular prism is given by the following formula


\begin{gathered} A=2\cdot l\cdot w+2\cdot l\cdot h+2\cdot w\cdot h \\ \text{where l is the length, w is the width and h is the height} \end{gathered}

replacing:


\begin{gathered} A=2\cdot11\cdot6+2\cdot11\cdot13+2\cdot6\cdot13 \\ A=132+286+156 \\ A=574 \end{gathered}
