Q3 is a good problem on one level, but a real gotcha on another. I wonder how many students forget to add in the margin measurements to get the total dimensions after going thru all the computing, especially if this question is given on a major exam....
For the cylinder in the sphere: would have been much easier to maximize the volume as a function of y instead of x. The first and second derivatives are simple (no derivatives of square roots)

This video is the best one
Great video! The cylinder one is so much easy if you draw the cylinder with it's height on the x axis

This is great stuff!
or these would be my latest materials for more practices

On Q6 shouldn't the constraint eqaution be 2x+2y=90 which simplifies to x+y=45
Where can I get the pdf list of these questions.
25:18 Why is it split in two??
Cause it is easier like this
