Cubic feet is a unit of volume. The question asks what is the volume of air inside the balloon, but doesn't give a time interval...

Ok well the balloon has 4.2 cubic feet of air to begin with then it goes to 5.6 cubic feet of air. The change is the difference between those two numbers.

ooh well the multiple choice is A. 25% B. 33.3% C. 75% D. 80% and i got 33.3% i just dont know how i would work the problem out

Ok 33.3% is correct. The change is 5.6-4.2=1.4 so you want to compare the change with the starting amount of air which is 4.2. So you get 4.2 divided by 1.4 to find the percentage of change in cubic feet which is 33.3%.
