Video Summary

Monica wants to stack glasses between two shelves that are 36 centimeters apart. We know a stack of eight glasses is 42 cm tall and a stack of two is 18 cm tall. Using equations, we find each additional glass adds 4 cm in height, and one glass is 14 cm tall. To fit the tallest possible stack, calculate starting with one glass (14 cm), then determine how many more can be added. Subtract 14 from 36 to get 22 cm, allowing for 5 additional glasses (at 4 cm each). Therefore, the largest number that fits is 6 glasses.
