AM having problems understanding what equations to use for this word problem. Please help.

A rectangular storage container with an open top is to have a volume of 48ft^3. The length of its base is twice the width. Material for the base costs $8 per square foot and material for the sides cost $6 per square foot. Find the cost of materials for the cheapest such container.
