The number of bytes for the Exabyte is listed as one pentillion, but I believe the correct answer is quintillion. Which is correct? ---

As per my research it is a quintillion. ---

Unfortunately, the answer keys are being posted by teachers. Ugh. Can something be done so these documents cannot be shared or copied? > **[Bytes%20and%20File%20Sizes%20HW%20-%20%20Answer%20Key.pdf](https://wbrowardhs.enschool.org/ourpages/auto/2016/8/19/35918768/Bytes%20and%20File%20Sizes%20HW%20-%20%20Answer%20Key.pdf)** ---

Yeah, really unfortunate. I will let the team know. ---

Just learned that under the advanced options in sharing, you can choose to not let others share, download or make a copy. ---

Hey folks, I’m following up on this to see if I can get this individual document taken down. We do our best to keep answer keys and exemplars in the hands of our verified teachers but it’s a constant challenge. We appreciate you helping us out. Thanks also @janderson for pointing out that feature. It’s one that we’ll look into more. It’s always a struggle to balance making these tools convenient to use but not so convenient that they end up on the open Internet. Cheers, GT ---

It’s 1 quintillion and I’ve fixed the associated exemplar. Thanks for pointing out the issue! ---

It’s called ethics … which I realize even as I type this that those reading it most likely already demonstrate it. Not the first time, not the last … nothing new under the sun. I am hoping that educational institutions will be able to gravitate more from trying to police unethical educators to helping people realize the benefit of learning as opposed to cheating. Perhaps it was an oversight, too. 🤷‍♀️ Glad you were able to take it down, though. I actually stumbled upon this because I was hoping someone would have created an answer key so I didn’t have to make my own for [this](https://docs.google.com/document/d/1aiCZucwRULkV7zhEwp-BUUVzwBXsIbBCr7Hv_EgWDro/template/preview). Hope y’all are having a great school year!
