Sagot :

The question requires us to calculate the surface area of the rectangular prism.

The formula to calculate the surface area is given to be:

[tex]A=2\left(wl+hl+hw\right)[/tex]

where l is the length, w is the width, and h is the height.

From the question, the following dimensions are provided:

[tex]\begin{gathered} l=2.5 \\ w=7 \\ h=9 \end{gathered}[/tex]

Therefore, we can calculate the surface area to be:

[tex]\begin{gathered} A=2(7\cdot2.5+9\cdot2.5+9\cdot7) \\ A=206\text{ in}^2 \end{gathered}[/tex]

OPTION C is correct.
