# Math Help - Application

1. ## Application

The weight of a liquid varies as its volume V. If the weight of the liquid in a cubical container 5 cm on a side is 250 g, find the weight of the liquid in a cubical container 4 cm on a side.

Help!

2. $V \propto w$

$V =k w$

Using the values stated

$5 = 250k$

$k = \frac{5}{250}=\frac{1}{50}$ and $V = \frac{1}{50} w$

Now make $V=4$
