A bit of basic practice on working backwards using volume formulae. The first 5 questions don’t require any square/cube rooting and the algebra is easier. From Q6 on it gets a little bit trickier. I wrote this as the exercises in the textbooks progressed too quickly for some of my class. I felt it would be good to help them slowly build some confidence before proceeding onto the harder questions in the textbooks. The diagrams are obviously not to scale, but I didn’t feel that was an important part of this initial task on working backwards.
