Calculate the density of an object, including the precision of measurements and calculations.

Here are the solutions to the problems.

: Density Calculation

• Instrument Precision:

  • Digital scale: $\pm 0.1$ g
  • Ruler (10 mm scale): $\pm 1$ mm or $\pm 0.1$ cm

• A. Average values for mass, length, width, and height including the residuals (uncertainties). The uncertainty for repeated measurements is taken as the larger of the instrument's precision or half the range of the measurements. The average value is rounded to the same decimal place as its uncertainty.

  • Mass ($M$):
    • Measurements: $9.2
