I am trying to teach my autistic son math so I am relearning as a 47 year old father who did poorly in school. Thanks to your website he and I have come along way. That being said we have come across a problem that I cannot find the solution to anywhere.
The surface area of the moon is 37 932 330 km square. Calculate the side length of a square with the same area.
Show your work.
I've seen many people demonstrate the way to calculate squares to large numbers, but this one having a 0 on the end makes it confusing as to how the answer is 6159 km.
Thank you Leslie James Hobe
