We invite you to test your GMAT knowledge for a chance to win! Each week, we will post a new Challenge Problem for you to attempt. If you submit the correct answer, you will be entered into that week’s drawing for a free Manhattan GMAT Prep item. Tell your friends to get out their scrap paper and start solving!
Here is this week’s problem:
An insect is located at one corner (point A) on the surface of a rectangular solid that measures 3 x 4 x 5 inches, as shown in the diagram.
Note: Figure is not drawn to scale.
If the insect crawls along the surface of the rectangular solid to the opposite corner (point B), what is the shortest possible length, in inches, of the insect’s path from point A to point B?
