So which one is it? Since 90cm(l) + 65cm(w) + 75cm(h) = 230cm is greater than 158cm.
Both rules apply
This means that you can have something that's 158cm total, but it cannot be longer than 90cm and cannot be wider than 65cm, and cannot be higher than 75cm. That doesn't mean that ALL sides can be maximum.
An example - you have something that is 65cm wide (max width) and 75cm high (max height), to fit in the maximum 158cm total the length can be no greater than 18cm (18+65+75 = 158)
