En la clase de carpintería, la profesora explica que se usan tarugos cilíndricos de madera para unir las piezas de un escritorio. Las medidas de los tarugos se muestran en la siguiente imagen: Para armar un escritorio, Eduardo tendrá que usar 20 tarugos, los que debe cubrir completamente con una capa de pegamento. Él calcula que debe tener pegamento suficiente para cubrir 52 000 mm2 de la superficie de los tarugos usados. Sin embargo, su compañera Francisca le dice que esa cantidad de pegamento no alcanzará para cubrir todos los tarugos.
