In this Cyberchase video clip, the team estimates a large number of penguins by breaking the group into 30 smaller clusters within a grid. The team notes that there are a different amount of penguins in each square, so they can't multiply to figure out the exact number of penguins. However, they estimate using a square with eight penguins, which is between the lowest and highest number of penguins per square. They multiply the 30 squares by eight penguins and get 240 penguins. Fluffy reminds them to estimate high so none of the penguins are left out, and they round the estimation up to 250.
