Boring, boring... (Posted on 2005-03-06) Difficulty: 4 of 5
You have a 3x3x3 cube. You bore a circular hole, of diameter 1, from the center of the top face to the center of the bottom face. You bore a similar hole from the left face center to the right face center, and another hole from front center to back center. How much material was removed?

A depiction of the void of my original picture, made the solid portion, is here.

Don't forget to cross your eyes, so the left eye sees the right image and vice versa.
