You have your definition for Enterprise Value flipped - it should be (Equity Value + Total Debt - Cash & Equivalents + Non Controlling Interest). If you are subtracting debt and adding cash, you are typically looking to get equity value from EV.

Your Box multiples look to be correct - looks like they trade at 6.1x on a trailing twelve month revenue basis, and ~5.0x on a next twelve months revenue basis.

Given that Dropbox has a $10BN valuation and a $600MM line of credit from the big banks, I would expect that their trailing revenue multiple is ~10.0x.
