Question

Please help me :'(

Including the bus driver, there are 15 people on a bus. During the bus ride, each person produces 750 BTUs (British thermal units). The interior of the bus measures 38 feet by 8.5 feet by 6.25 feet.

How many BTUs per cubic foot are produced?

Enter your answer, rounded to the nearest hundredth. (Is it 2.69?)

Answer 1

First find the total BTU's by multiplying 750 by 15.

750 * 15 = 11,250 Total BTU's.

Next find the volume of the bus by multiplying the length by the width by the height.

Volume = 38 x 8.5 x 6.25 = 2,018.75 cubic feet.

Final step, divide the Total BTU's by the Volume of the bus.

11,250 / 2,018.75 = 5.57 BTU's per cubic foot.
