Question

一张纸由六个连在一起的正方形组成，标记如图所示。沿正方形的边折叠后形成一个立方体。与标有 $X$ 的面相对的面，其标记是

A piece of paper containing six joined squares labeled as shown is folded along the edges of the squares to form a cube. The label of the face opposite the face labeled $X$ is

$Z$

$U$

$V$

$W$

$Y$

答案：E

知识点：展开图（立体几何）正方体

难度评级：920

解答：

把这个展开图折成让 $X$ 成为底面。那么 $U$ 、 $V$ 、 $W$ 、 $Z$ 会围成四个侧面。

唯一剩下的正方形 $Y$ 成为顶面，与底面 $X$ 相对。

所以正确答案是 E。

Fold the net so that $X$ is the bottom face. Then $U,$ $V,$ $W,$ and $Z$ wrap around to become the four side faces.

The only remaining square, $Y,$ becomes the top face, which is opposite the bottom face $X.$

Thus, the correct answer is E .
