Students will solve the “face-to-face” problem in the cube. In exams, there are often some problems that determine which sides of the cube are relative, and the two most common types of problems are two. Figure 1 is a plane expansion plan of a cube, where is the word on the opposite side of the “zu” character from the “繁” character? Analysis of the word: we can see in Figure 1 “Sheng ” where the word is seen as positive, “Chang ” where the word is seen as the left, “Fan ” where the word is seen as Above, then “Rong” where the word is the right side, “Zu ” where the word is back, “country ” where the word is below.
