Question

Mason takes a box, which is in the form of a cube. He colors one of the faces of the box, and draws a triangle and a rectangle on two of the faces, leaving the other faces blank, as shown below.
Later, Mason's brother, James, unfolds the box such that the colored face appears on the top.
Which of the following images correctly represents the pattern on the unfolded box?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D


From the cubical box, we can say that the colored face, and the faces with the triangle and with the rectangle share the same vertex, as shown above using a circle.

Thus, we can look at the options in which the three faces share the same vertex.

Hence, the unfolded box will look like the one below, i.e., with the same vertex among the three faces.
