During strenuous work a human body generates about 2,400 btus of body heat per hour. if 6 football players are in a gym that is 12 ft × 18 ft × 10 ft lifting weights, how many btus per cubic foot do they produce in 2 hours? (to the nearest tenth)

Given that energy produce by working out by the human body is 2,400 btu per hour per persons. 6 football player
v = 12 ft x 18 ft x 10 ft

E = ( 2400 Btu/ person hr) ( 2 hrs ) ( 6 persons ) / ( 12 ft x 18 ft x 10 ft )
E = 13.3 BTU / cu ft is they energy of 6 football player produce in working out for 2 hrs
