I'm Gonna Get You!

Geometry Level 4

In a rectangular room with dimensions 30' by 12' by 12', a spider is located in the middle of a 12' by 12' wall one foot away from the ceiling. A fly is in the middle of the opposite wall one foot away from the floor.

If the fly remains stationary, what is the shortest total distance in feet that the spider must crawl along the walls, ceiling, and floor in order to capture the fly?


The answer is 40.
