Including the bus driver there are 20 people on the bus. during a one hour ride, each person produces 740 btus. the interior of the bus measures 38 ft by 8.25 ft by 7.5 ft. how many btus per cubic foot are produced? enter your answer rounded to the nearest hundredth.

Given:
20 persons
each person produces 740 BTUs 
Dimension of bus interior: 38 ft by 8.25 ft by 7.5 ft. 

Find how many BTUs per cubic foot are produced.

BTU stands for British Thermal Unit. It is an energy unit.

20 person * 740 BTU per person = 14,800 BTU

Volume of the bus = 38 ft * 8.25ft * 7.5 ft = 2,351.25 cubic feet

14,800 BTU / 2,351.25 cubic feet = 6.29 or 6.30 BTU per cubic foot

The answer is 225 miles per 4.5 hours. hope this ; )
