Question 522767: The weight of a liquid varies directly as it's volume V. If the weight of the liquid in a cubical container 3 cm on a side is 81g, find the weight of the liquid in a cubical container 5cm on a side?
My instructor is having us solve these problems with Direct Variations using the formula y=kx

The weight of a liquid varies directly as it's [sic] volume V. If the weight of the liquid in a cubical container 3 cm on a side is 81g, find the weight of the liquid in a cubical container 5cm on a side?
----------------------
Volume is a function of the cube of the side of a cube
81:3^3::W:5^3
27W = 81*125
W = 375 g
Some very dense water.

PS it's = it is
