3. Professor Martinez wants to make a rectangular box with an open top to hold all her Christmas cookies. She designs the box so that it has a volume of 10in3and the length of its base is twice the width. After going to a local craft store, she also finds that the base costs $10 per square inch. Material for the sides cost $6 per square inch. a. Sketch and label a diagram illustrating this situation and label it. b. Find the dimensions that will result in a box with the lowest cost. Your work must include work showing that your answer is, in fact, the lowest cost
