Question

Twenty-seven people skated their hearts out at big Ben's birthday party at the skating rink last night, each producing an amazing 2,400 BTUs (British Thermal Units) of heat while listening to an hour's worth of Beatles, Spice Girls and Adele. The interior of the skating rink is 120 feet long, 35 feet wide and and 20 feet tall. To the nearest thousandth (3-decimal places), how many BTUs per cubic foot did they produce?

Answer 1

0.771 BTU/cubic ft

Explanation:

Volume = 120*35*20 = 84,000cubic ft

Total BTU's = 2,400* 27 = 64,800BTU

64,800 BTU / 84,000 cu ft = 0.771 BTU/cubic ft
