Take a square sheet and fold it left onto right, then fold the folded half again left onto right into a narrow strip. One straight cut is made down the middle of the strip along the dashed red line. Into how many pieces does the sheet fall when opened?

Question

Accepted Answer

5. The strip has 4 layers, so the single cut becomes 4 parallel cuts running right across the opened sheet from top to bottom. 4 such cuts make 4 + 1 = 5 pieces.
