Sand topdressing by exact depth: how to work it out

Today I explained the same calculation about sand topdressing for the third time, so I need to write a blog post on this topic. This is following the method of David Robinson, who says when you’ve written the same code 3 times, write a function; when you’ve given the same advice 3 times, write a blog post; and when you’ve done the blog post 3 times, write a book.
