Which of the following cube in the answer figure CANNOT
be made based on the unfolded cube in the question figure?Solution
From 'A, R, T', 'A' is on the opposite face of 'T'. From 'D, U, E' 'D' is on the opposite face of 'E'. 'R' is on the opposite face of 'U'. In option 'A', this cube can be made by folding the given unfolded cube. In option 'B', this cube can be made by folding the given unfolded cube. In option 'C', this cube can be made by folding the given unfolded figure. In option 'D', 'R' and 'U' cannot be on adjacent faces. Thus, this cube cannot be made by folding the given unfolded cube. Hence, option d.
