Question

:

30 students return to the classroom after playing outside at recess. Over the course of the next hour, each person produces 800 BTUs (British Thermal Units)of heat. The room is 20 feet by 20 feet by 12 feet. How many BTUs per cubic foot were produced?

Answer 1

5 BTUs/ft^3

Explanation:

800 BTUs * 30 students = 24000 total BTUs combined

Volume of room = 20 feet * 20 feet * 12 feet = 4800 cubic feet

BTUs/ft^3 = 24000 BTUs / 4800 cubic feet = 5 BTUs/ft^3

So the amount of BTUs per cubic foot that were produced was 5 BTUs/ft^3
