Answer
The surface area of the rectangular solid is\[96\text{ f}{{\text{t}}^{2}}\].
Work Step by Step
Each edge of the cube (s) is 4 ft. The surface area of the cube can be computed by multiplying square of edge with 4. Compute the surface area of the cube using the equation as shown below:
\[\begin{align}
& \text{Surface area of the cube}=\left( 6\times 4\text{ f}{{\text{t}}^{2}} \right) \\
& =96\text{ f}{{\text{t}}^{2}}
\end{align}\]
