Chapter 13.3, Problem 14P

The front (and back) of a greenhouse have the shape and dimensions shown in Figure 13.36 . The greenhouse is 40 ft long, and the angle at the top of the roof is 90°. A fungus has begun to grow in the greenhouse. so a fungicide will need to be sprayed. The fungicide is simply sprayed into the air. To be effective, 1 tablespoon of fungicide is needed for every cubic yard of volume in the greenhouse. How much fungicide should be used? Give your answer in terms of units that are practical. (For example, it would not be practical to have to measure 100 tablespoons, nor would it be practical to have to measure 3.4 quarts. But it would be practical to measure 1 quart and 3 fluid ounces.)
