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.
