The problem says that V(x) varies directly with its length. This is a proportionality problem. So, V(x) = kl. If you are given a length of 25 inches and a k (proportionality constant) of 15, you are required to find its volume V(x).

V(x) = kl
V(x) = (15) (25 inches)
<u>V(x) = 375 cubic inches</u>

The volume of the box is 375 cubic inches.
