Question

Mr. De Leon's Geometry class has 34 students. After lunch everyone returns to the classroom. Within an hour, each person produces 800 BTUs. The room is 25 feet by 32 feet by 12 feet. How many BTUs per cubic foot were produced?
Plz provide the work.

Answer 1

Answer:

2.833  BTUs per cubic foot were produced.

Step-by-step explanation:

BTU's produced by one person = 800

No. of students = 34

Therefore no. of  BTU's produced by 34  person = 800 * 34 = 27,200 BTU

Dimension of class  25 feet by 32 feet by 12 feet

Volume of class = length * width * height = 25 * 12 * 32 = 9,600 cubic feet

________________________________________________

BTUs per cubic foot  produced = Total  BTU's produced by 34  person/ Volume of class

Substituting the value of Total BTU produced and volume of class

BTUs per cubic foot  produced =  27,200 BTU/  9,600 cubic feet

                                                    = 2.833 BTUs per cubic foot

2.833  BTUs per cubic foot were produced.
