Answer:

Option B. [tex]119.2\ in^{2}[/tex]

Step-by-step explanation:

we know that

The surface area of the box is equal to

[tex]SA=2B+Ph[/tex]

where

B is the area of the base of the box

P is the perimeter of the base of the box

h is the height of the box

Find the area of the base B

[tex]B=4.4*5=22\ in^{2}[/tex]

Find the perimeter of the base P

[tex]P=2(4.4+5)=18.8\ in[/tex]

The height is [tex]h=4\ in[/tex]

substitute the values

[tex]SA=2(22)+18.8(4)=119.2\ in^{2}[/tex]
