The elevation of the basement floor in a building is -14 ft. The elevation of the roof is 36 feet. What is the distance from the basement floor to the roof?

The distance from the basement floor to the roof is the sum of the elevations, which is:

36 ft - (-14 ft) = 36 ft + 14 ft = 50 ft

Therefore, the distance from the basement floor to the roof is 50 feet.
