Answer 1

Step-by-step explanation:

The answer is equal to the surface area of the box. So, the surface area can be calculated as:

A = 2lw + 2wh + 2lh

Where l is the length, w is the width and h is the height of the box.

So, replacing l by 10 in, w by 5 in, and h by 3 in, we get:

A = 2(10 in)(5 in) + 2(5 in)(3 in) + 2(10 in)(3 in)

A = 100 in² + 30 in² + 60 in²

A = 190 in²

Therefore, the area is 190 in².
