Carla, Grant, and Tyra boarded an airplane in Dallas bound for San Francisco. Grant found out that each passenger was allowed to bring one piece of carry-on luggage. The rule was that the height, length, and width of the bag must add up to 45 inches or less. Which bags meet the size restriction?
Carla: Grant: Tyra:
20in x 14in x 8in in x 10in x 7in 14in x 14in x 14in
When they got to the airport they saw this sign. Which bags will the airline allow onto the plane as carry-on luggage following the second size, restriction?
Carla said, “It would be simpler if the rule gave a maximum for a
bag’s volume instead of dimensions. Which of the three friends
could bring their bags onto the plan if the airline used this volume rule?
Why might the airline not want to use this rule?
