Answer 1

The volume of a box(V) varies directly with its length(l). If a box in the group has a length of 30 inches and k = 24, what is its volume?
720 cubic in.
600 cubic in.
1.25 cubic in.<--------

Answer 2

Because volume affects length directly, we write this as v=kl. From here, we can fill in the blanks to get v=(24)(30). The answer from here should be pretty straightforward. Just multiply the two to get v=720.

Answer: 720
