The human body generates about 400 BTUs of body heat per hour while active. If an office that is 18 ft × 38 ft × 12 ft has 12 workers, how many BTUs per cubic foot do they produce in 5 hours? (to the nearest tenth)

Answer:

2.9 BTU/ft³

Step-by-step explanation:

Total BTU = 12 workers × (400 BTU/1 worker·hour) × 5 hours = 24 000 BTU

V = lwh = 38 ft × 18 ft × 12 ft = 8208 ft³

24 000 BTU/8208 ft³ = 2.9 BTU/ft³
