Study Notes
Measurements and Units
- A stack of paper comprises 500 sheets.
- Dimensions of the stack: 0.297 m (length) x 21.0 cm (width) x 50.0 mm (height).
- Thickness of one sheet of paper can be calculated by dividing the height of the stack by the number of sheets.
Volume Calculations
- To find the volume of the stack of paper in cm³:
- Convert all dimensions to centimeters:
- 0.297 m = 29.7 cm
- 21.0 cm = 21.0 cm
- 50.0 mm = 5.0 cm
- Use the formula: Volume = length x width x height.
- Convert all dimensions to centimeters:
SI Units for Measurement
- Length Units:
- 1 dm = 0.1 m
- 1 cm = 0.01 m
- 1 mm = 0.001 m
- 1 µm = 0.000001 m
- 1 km = 1000 m
- Volume Units:
- 1 cm³ = 0.000001 m³
- 1 dm³ = 0.001 m³
Measuring Volume by Displacement
- Volume of an object that floats can be determined using water displacement.
- Procedure involves submerging the object in water and measuring the volume of water displaced.
- Diagram reference (Figure 1.8) illustrates the method with a block of wood floating on water.
Key Equation
- Important for calculations involving conversions and volume measurements.
