How do you determine the amount of sand or gravel needed for an area?

By graduating from the 8th grade. Or high school diploma, if its from a
public school.

Schools must be worse than I thought if it takes the 8th grade to be
able to do that. It is basic math and any 4th grader at the latest
would be able to do it in my time.
