Priya folds a square sheet along its diagonal, then folds the triangle along the dotted vertical line, so that a flap (darker) lies over part of it. She punches three holes as shown. How many holes will the opened sheet have?

Question

Accepted Answer

8. The diagonal fold makes 2 layers everywhere. The flap of the second fold covers only part of the piece: 4 layers under the flap, 2 elsewhere. The hole on the flap makes 4 holes and the other two make 2 each: 4 + 2 + 2 = 8 .
