Example 1.1
Each side of a cube is measured to be 7.203 m. What are the total surface area and the volume of the cube to appropriate significant figures?
Answer: The number of significant figures in the measured length is 4. The calculated area and the volume should therefore be rounded off to 4 significant figures.
Surface area of the cube = \( 6(7.203)^2 \text{m}^2 = 311.299254 \text{m}^2 = 311.3 \text{m}^2 \)
Volume of the cube = \( (7.203)^3 \text{m}^3 = 373.714754 \text{m}^3 = 373.7 \text{m}^3 \)
About Significant Figures
The side length of 7.203 m has 4 significant figures. When calculating surface area and volume, the results should be rounded to maintain this precision:
- Surface Area = 6 × (7.203)² = 311.299254 → 311.3 m²
- Volume = (7.203)³ = 373.714754 → 373.7 m³
