Question: If a paper is folded in half three times, how many layers are there?

Options:

Correct Answer: 32

Solution:

Folding a paper in half three times results in 8 layers (2^3 = 8).

If a paper is folded in half three times, how many layers are there?

If a paper is folded in half three times, how many layers are there?

Step 1: Start with one piece of paper. This is your initial layer.
Step 2: Fold the paper in half for the first time. Now you have 2 layers (1 x 2 = 2).
Step 3: Fold the paper in half for the second time. Now you have 4 layers (2 x 2 = 4).
Step 4: Fold the paper in half for the third time. Now you have 8 layers (4 x 2 = 8).
Step 5: You can also use the formula 2^n, where n is the number of folds. Since you folded it 3 times, calculate 2^3, which equals 8.

Exponential Growth – Understanding how folding a paper in half increases the number of layers exponentially, specifically using powers of 2.
