Worked solutions to part A and B of the 2019 higher maths paper 2 differentiation optimisation question. Part A can be tricky at first and there is a lot of work to do for just 3 marks but I have tried my best to break it down and explain it.

Explore the detailed solution for optimizing the surface area of a cuboid box with a tunnel, as presented in the SQA Higher Mathematics 2019 exam. This study note covers the derivation of the surface area formula, the application of differentiation to find minimum values, and step-by-step explanations for both parts A and B of the question. Ideal for students preparing for optimization problems in mathematics.
