Un vaso de tubo de 2 cm de radio se llena hasta la mitad de agua. Si se echa un cubito de hielo en forma de hexaedro de 3 cm de arista, ¿qué altura subirá el agua?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
