Answer 2

the size of the box is 45"

Explanation:

screen measures 36 inches wide by 27 inches high

The diagonal of the box is the size you see on the box.

Lets find the diagonal of the box using pythagorean theorem

`c^2= a^2 + b^2`

Where 'a' is the length and 'b' is the width

`c^2= 27^2 + 36^2`

`c^2= 729+1296=2025`

Now take square root on both sides

c=45

So the size of the box is 45"
