Can you solve the birthday cake riddle?

Your friend's birthday is tomorrow, and he's turning... well... you've forgotten. A ginormous cake has been prepared and your job is to sculpt his age as the chocolate centerpiece. The birthday boy is a giant, and you're afraid that if your forgetfulness becomes known, you'll become part of the feast. Can you figure out your friend's age before the party? Marie Brodsky shows how. [Directed by Igor Coric, Artrake Studio, narrated by Addison Anderson, music by Cem Misirlioglu].
