Question

Many airlines have limits on the size of carry-on baggage that a passenger may have. One airline's rule is that l + w + h must be less than 50 inches, where l is the length, w is the width, and h is the height of a bag. Will a bag with the following dimensions be allowed?l = 20 inchesw = 18 inchesh = 11 inchesyesno

Answer 1

Add l+w+h if l=20in, w=18in and h=11in:

$l+w+h=20in+18in+11in=49in$

Since 49 is less than 50, then a bag with those dimensions will be allowed.

Therefore, the answer is: yes.
