Word problem

  1. Nov 12, 2004 #1
    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?
