Cyberchase: Barrel Bridge
Math → Measurement → Estimation
The CyberSquad encounters a hole in the ice, and there is no way around it. The group looks in a nearby shed and finds barrels, which it uses to estimate the size of the hole. Digit helps the group estimate that 12 additional barrels will sufficiently fill the hole. The CyberSquad fills the hole with its remaining 11 barrels and crosses the barrel bridge successfully.
