I'm having problems setting up this problem (word problems are my worst downfall!)

a rectangular container with an open top is to have a volume of 10 meters cubed. The length of its base is 2x the width.
The cost of the base is $12 per sq meter. The cost of the sides is$5 per sq meter. find the cost fo the materials for the cheapest container. :yuck:

Can you write equations for the volume and cost of the container in terms of it's dimensions? Can you write equatiosn for the dimensions in terms of each other?
