How do you figure the average height of a 60 ft long wall that is 4 ft on one end and 1 ft on the other?
If the wall is sloped uniformly then the length of the wall is irrelevant and the average height is (4+1)/2 = 2.5 feet. If the wall is not uniformly sloped you have no chance of answering the question!
How many feet of wall paper is in an average roll?

What is a horizontal exit door?
It is a 1 1/2 hour fire rated door embedded along a 2 hour fire rated wall that creates an exit to safety inside of a building. Codes give maximum travel distances to get to safety, i.e. to exit a building. However, some buildings are so large (Casino's, Hotels, Convention Centers) that it is impossible to get someone out of the facility within the maximum distance. Therefore, to comply with the code, a fire rated wall is constructed with fire rated doors to contain the fire and allow occupants to exit into a safe part of the building.
