Me at work, putting away overstocks. I need to write the quantity on them. Hmmmm... 3 boxes deep x 6 boxes wide x 12 per box = 18 x 12 = I don't feel like calculating that. Think think think...

3 x 6 x 12
= 3 x 3 x 2 x 2 x 2 x 3
= 2³ x 3³
= 8 x 27
= 216

Seriously, if you don't use math at work, I don't think you're actually doing any work.

(And yes, I could have done 3 x 72 instead which would have been simpler, but the prime factorization was so obvious it distracted me.)
