This is a simple, interdisciplinary worksheet for science or math students. It walks students through the steps of figuring out how many times bigger the sun is compared to the earth (by diameter, and then by volume).
The first page of the document is the worksheet; the second page is the answer key.
Primarily written for an Earth Science or Astronomy class, but can be useful in a Math class, too. The math involves substituting numbers into an equation and simplifying (cubing, multiplication, and division).
