Math Puzzle for March 6, 2026

A barrel of viscous fun for the whole family

Alameda Post - A cylinder with text on it that says "Hair gel Avoid skin contact. Keep Away from open flame. 80 calories per serving."

Tristan is computing the volume of a cylindrical barrel using a thin measuring rod. He pokes the measuring rod in the bung hole, located at the middle of the barrel. The measuring rod shows that 53 centimeters of the rod are inside the barrel.

Find largest possible volume for the barrel given his exacting measurement.

Last week’s winner was Ben Chacon with 24 grams.

Use of AI to solve this problem is morally equivalent to training wheels on a tricycle.
