Nigel · Answer 1

To determine the amount of heat produced per cubic foot in a given period of time. We simply multiply the heat per hour to the number of hours and divide the resulting value with the volume.

400 BTU / hr (5 hr) = 2000 BTU

2000 BTU / (18) (38) (12) = 0.2 BTU / ft^3 x 12 = 2.9 BTU/ft^3
