Answer:
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 = [tex]20 ft\times 30 ft\times10 ft[/tex]
= [tex]6000 ft^3[/tex]
Human body generates BTUs of body heat per hour = 400
So, BTUs produced in 3 hours = [tex]400 \times 3[/tex]
= [tex]1200[/tex]
1 human body produce BTUs in 3 hours = 1200
8 human body produce BTUs in 3 hours = [tex]1200 \times 8[/tex]
= [tex]9600[/tex]
So, they produce BTUs per cubic foot = [tex]\frac{9600}{6000}[/tex]
= [tex]1.6[/tex]
Hence they produce 1.6 BTUs per cubic foot in 3 hours.
