Answer:

$SA=700\text{ square ft}$

Explanation:

The surface area of a rectangular prism is represented by the following equation:

$\begin{gathered} SA=2lw+2wh+2lh \\ where, \\ l=\text{ length} \\ w=\text{ width} \\ h=\text{ height} \end{gathered}$

Therefore, for the given rectangular prism:

$\begin{gathered} SA=2(20)(10)+2(10)(5)+2(20)(5) \\ SA=400+100+200 \\ SA=700\text{ square ft} \end{gathered}$
