Hi,

I am posting a question from the topic Optimization in Calculus I. The prerequisite in solving this question :

a) Understanding of global maxima and global minima using the first and second derivative tests.

b) Differentiation rule.

Question :

A rectangular storage container with an open top is to have  a volume of 10m310�3. The length of its base is twice the width. Material for the base costs $10$10 per square meter. Material for the side costs $6$6 per square meter. Find the cost materials for the cheapest such container.
