Question

Suppose that 50 people sitting in an enclosed room are each generating about 400BTUs of body heat per hour. If the room is 5oft x 4oft x 12ft, how many BTUs percubic foot do they produce in 6 hours? Round your answer to the nearest hundredth.

Answer 1

First, let's calculate the volume of the room:

`50ft\cdot40ft\cdot12ft=24,000\text{ }ft^2`

Now, if in 1 hour 50 people generate 400 BTU, in 6 hours, they generate:

`400\cdot6=2400`

Then, to find the quatity of BTU in the volume of the room, we divide the volume by the BTU:

`(24,000)/(2,400)=10`

The answer is 10 BTU per cubic feet.
