Why is a mathematical equation that I wrote on my cars paint with a marker such an attraction for people?

People keep stopping and looking and talking about it and in many cases take a pictures of it. Little do they know I'm still in my car tinted out car watching them do this.

I wrote; Vol x 3 divided by 4 divided by Pi cube routed x 2 =

Some man and his wife just stopped and started talking about it just now as I'm writing this question. Somebody stop me!

people are entertained by things they don't understand. Not the math equation, but why you wrote it on your car.
