Question

A total of 1,000 BTUs are needed to cool a space. If 2.5 BTUs are needed to cool 1 cubic foot of space, what is the maximum volume of space that 1,000 BTUs will cool?

Answer 1

400 ft³

Explanation:

Dimensional analysis can help you figure this out.

(1000 BTU)/(2.5 BTU/ft³) = (1000/2.5) ft³ = 400 ft³

1000 BTU can cool up to 400 cubic feet of space.
