A rectangular, lidless storage container must have a volume of 10 m³. The length of its base is twice its width. The material for the base costs $10 per square meter, and the material for the sides costs $6 per square meter. Find the cost of the materials that will make the container the cheapest. I will explain the exercise step by step using calculations and a graph, using the GeoGebra graphing calculator.
