The human body generates about 400 btus of body heat per hour while active. if an office that is 20 ft × 30 ft × 10 ft has 8 workers, how many btus per cubic foot do they produce in 3 hours? (to the nearest tenth)

a)0.1 btus/ft3
b)0.2 btus/ft3
c)0.5 btus/ft3
d)1.6 btus/ft3

1.6 BTUs per cubic foot

Step-by-step explanation:

We are given the dimensions  of an office 20 ft × 30 ft × 10 ft

Volume of office =

                            =

Human body generates BTUs of body heat per hour = 400

So, BTUs produced in 3 hours =

                                                  =

1 human body produce BTUs in 3 hours = 1200

8 human body produce BTUs in 3 hours =

                                                                    =  

So, they produce BTUs per cubic foot =

                                                                =

Hence they produce 1.6 BTUs per cubic foot in 3 hours.
