Answer:

The surface area of the box is [tex]SA=274\ in^2[/tex]

Step-by-step explanation:

we know that

The surface area of a box is equal to

[tex]SA=2HL +2LW +2HW[/tex]

In this problem

Let

[tex]L=13\ in[/tex]

[tex]W=4\ in[/tex]

[tex]H=5\ in[/tex]

substitute the given values in the formula

[tex]SA=2(5)(13) +2(13)(4) +2(5)(4)[/tex]

[tex]SA=130 +104 +40[/tex]

[tex]SA=274\ in^2[/tex]
