30 students return to the classroom after playing outside at recess. Over the course of the next hour, each person produces 800 BTUs (British Thermal Units)of heat. The room is 20 feet by 20 feet by 12 feet. How many BTUs per cubic foot were produced?

answer: slight chance that it will happen

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
