One noon, it rained heavily. Xiao Fang asked Xiaohua if it would be sunny after 84 hours. Xiaohua said it might not be a small house.

84 ÷ 24 = 3 ... 12, which means there are three days in 84 hours 12 hours, which means three and a half days. It takes three days or noon in the same place, and then it takes 12 hours at midnight. Since it is late at night, you can't see the sun. So Xiao Fang is right.
