An exercise class had 18 people. if each person produced 1,900 btus of body heat during the class and the room is 28 ft × 32 ft × 12 ft, how many btus per cubic foot did they produce? (to the nearest hundredth)

 Number of BTU's per cubic foot is 3.18 BTUs/cubic ft.

Step-by-step explanation:

Since we have given that

Number of people = 18

BTU produced by each person = 1900

Total BTU produced by 18 persons is given by

Dimension of the room is given by

Length of room = 28 ft

Width of room = 32 ft

Height of room = 12 ft

So, Volume of room is given by

So, Number of BTU's per cubic foot is given by
