Calculating the Mass of One Sheet of Paper for a 13-Year-Old Student

Let's break down the problem step by step.

Given:

• Number of sheets = 500 (this info is extra and not directly needed for the mass of one sheet)
• Mass of 1.0 m² of paper = 0.080 kg
• Length of one sheet = 0.300 m
• Width of one sheet = 0.210 m

Goal: Find the mass of one sheet of paper.

Step 1: Calculate the area of one sheet

The area A = length × width

A = 0.300 m × 0.210 m = 0.063 m²

Step 2: Use the mass per unit area to find the mass of one sheet

The mass of paper per square meter is 0.080 kg/m².

Mass of one sheet = area of one sheet × mass per square meter

Mass = 0.063 m² × 0.080 kg/m² = 0.00504 kg

Step 3: Express the answer clearly

The mass of one sheet of paper is 0.00504 kg, or about 5.04 grams.

Summary: To find the mass of one sheet, multiply its area by the mass per square meter. Here, the mass is approximately 5 grams per sheet.
