A spider lived in a room that measured 30 feet long by 12 feet wide by 12 feet high. One day, the spider spied an incapacitated fly across the room, and of course wanted to crawl to it as quickly as possible. The spider was on an end wall, one foot from the ceiling and six feet from each of the long walls. The fly was stuck one foot from the floor on the opposite wall, also midway between the two long walls. Knowing some geometry, the spider cleverly took the shortest possible route to the fly and ate it for lunch. How far did the spider crawl?

Question
Transcribed Image Text:A spider lived in a room that measured 30 feet long by 12 feet wide by 12 feet high.
One day, the spider spied an incapacitated fly across the room, and of course wanted to
crawl to it as quickly as possible. The spider was on an end wall, one foot from the ceiling
and six feet from each of the long walls. The fly was stuck one foot from the floor on the opposite
wall, also midway between the two long walls. Knowing some geometry, the spider cleverly
took the shortest possible route to the fly and ate it for lunch. How far did the spider crawl?
