Answer 1

It looks like some words/numbers are missing. The general method (with the blanks filled) is:

- You would first use the Pythagorean Theorem on the bottom rectangle of the box to find the diagonal CB:
CB = sqrt(length^2 + width^2).

- Then use CB as a leg of the right triangle ACB, with AB being the hypotenuse:
AB = sqrt(CB^2 + height^2).

Combining the two steps:
AB = sqrt(length^2 + width^2 + height^2).

If you give the box’s length, width and height (or upload the picture with the numbers), I’ll compute the numerical approximation for AB.
