The surface area for a rectangular prism is given to be:


A=2(lw+lh+wh)

where l, w, and h are the lengths of the solid.

From the question, we have:


\begin{gathered} l=2\text{ cm} \\ w=5\text{ cm} \\ h=7\text{ cm} \end{gathered}

Therefore, the volume is calculated to be:


\begin{gathered} A=2((2*5)+(2*7)+(5*7)) \\ A=2(10+14+35) \\ A=2(59) \\ A=118\text{ cm}^2 \end{gathered}

The surface area is 118 square centimeters.
