Answer: OPTION D
Explanation:
The formula for calculate the surface area of a rectangular prism is:
Where w is the width, h is the height and l is the length.
You can see in the figure attached that:
l=3.4ft
w=3ft
h=4.1ft
Therefore, when you substitute these values into the formula you obtain that the surface area is:
![SA_(rp)=2[(3ft*4.1ft)+(3.4ft*3ft)+(3.4ft*4.1ft)]=72.88ft^(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ergdh0de4yedf5e21mlw5lp22q7hdvshro.png)
