Jessica would like to make a small notebook from A4 paper. She cut it into 4 and then sew the pieces together. If she has 40 sheets of A4 paper, how thick is the notebook?
Answer is 320 Pls answer with working out & method
4 small sheets for each piece of paper
4*40 = 160 sheets
2 pages per sheet, right?
So is 160 the answer because i might be wrong
To determine the thickness of the notebook made from 40 sheets of A4 paper, we need to first calculate the thickness of each sheet and then add them up.
1. Start by determining the thickness of a single sheet of A4 paper. The standard weight of A4 paper is usually around 80 g/m², and the most commonly used thickness is 0.1 mm (millimeters). However, to get a more accurate result, let's assume the thickness of each A4 sheet is 0.09 mm.
2. Since Jessica has 40 sheets of A4 paper and she cut each sheet into 4 pieces, the total number of small pieces she has is 40 * 4 = 160.
3. Now, to calculate the thickness of each small piece, divide the thickness of a single A4 sheet by 4:
Thickness of each small piece = 0.09 mm / 4 = 0.0225 mm.
4. Finally, to find the thickness of the notebook, multiply the thickness of each small piece by the total number of small pieces:
Thickness of the notebook = 0.0225 mm * 160 = 3.6 mm.
Therefore, the thickness of the notebook made from 40 sheets of A4 paper is approximately 3.6 millimeters.
