Question

Elyse folded a piece of paper in half 3 times. She then punched 3 holes in the paper. How many holes are in the paper when she unfolds it?

Answer 1

There are 24 holes in the paper, once it's all said and done. Every fold doubles the amount of original holes, so 3x2 is 6, 6x2 is 12, and then 12x2 is 24.

Answer 2

24 holes.

Explanation:

Elyse folded a piece of paper in one half then total surfaces of the paper will become 2.

Then the paper with 2 surfaces again folded half. Surfaces formed again will be 2×2 = 4

Similarly, This paper is folded again for the third time then the surfaces become 2×2×2 = 8

Now Elyse punched a hole in this folded paper so the total holes formed will be on all surfaces = 8.

Now if we punch 3 holes then total holes in unfolded paper will be = 8×3 = 24 holes

Therefore, 24 holes will be formed when paper is unfolded.
