The greatest distance will be the distance of diagonally opposite points. So, we can have a right angled triangle such that Height is 8 and radius is 8.

So, using Pythagoras theorem, we have $$sqrt(8^2 + 8^2 ) = sqrt(128)$$.

Attachment:

Use Pythagorus theorem -

Greatest distance is the diameter of the ( Square / Rectangle) = $$\sqrt{(8^2) + (8^2)}$$ =>$$\sqrt{128}$$
