SAT Math Multiple Choice Practice Question 164: Answer and Explanation
10. Which of the following patterns could be folded up into a six-sided rectangular box, without making any cuts?
Correct Answer: E
E. Choices (A) and (B) aren't the right shapes to be folded up into boxes, so you can eliminate them right away. Choices (C) and (D) are the right shapes, but you'd have to match a 6-cm side with a 5-cm side, and doing so would leave gaps in the box. Only Choice (E) fully closes up the box.
