Q. The volume of a rectangular prism is 480 cm3 480 \mathrm{~cm}^{3} . David measures the sides to be 66.4949 cm \mathrm{cm} by 9.99 cm 9.99 \mathrm{~cm} by 8.41 cm 8.41 \mathrm{~cm} . In calculating the volume, what is the relative error, to the nearest hundredth.\newlineAnswer:
  1. Calculate Volume: Calculate the volume of the rectangular prism using the measured sides.\newlineVolume = Length×Width×Height\text{Length} \times \text{Width} \times \text{Height}\newlineVolume = 6.49cm×9.99cm×8.41cm6.49\,\text{cm} \times 9.99\,\text{cm} \times 8.41\,\text{cm}
  2. Perform Multiplication: Perform the multiplication to find the calculated volume.\newlineCalculated Volume = 6.49×9.99×8.416.49 \times 9.99 \times 8.41\newlineCalculated Volume 54.5809×8.41\approx 54.5809 \times 8.41\newlineCalculated Volume 458.903289 cm3\approx 458.903289 \text{ cm}^3
  3. Find Absolute Error: Find the absolute error by subtracting the given volume from the calculated volume.\newlineAbsolute Error = Calculated VolumeGiven Volume|\text{Calculated Volume} - \text{Given Volume}|\newlineAbsolute Error = 458.903289 cm3480 cm3|458.903289 \text{ cm}^3 - 480 \text{ cm}^3|\newlineAbsolute Error \approx 21.096711 cm3| -21.096711 \text{ cm}^3|\newlineAbsolute Error \approx 2121.1010 \text{ cm}^33 (rounded to the nearest hundredth)
  4. Calculate Relative Error: Calculate the relative error by dividing the absolute error by the given volume and then converting it to a percentage.\newlineRelative Error = (Absolute Error/Given Volume)×100%(\text{Absolute Error} / \text{Given Volume}) \times 100\%\newlineRelative Error = (21.10cm3/480cm3)×100%(21.10 \, \text{cm}^3 / 480 \, \text{cm}^3) \times 100\%
  5. Perform Division and Multiplication: Perform the division and multiplication to find the relative error percentage.\newlineRelative Error (0.0439583333)×100%\approx (0.0439583333) \times 100\%\newlineRelative Error 4.40%\approx 4.40\% (rounded to the nearest hundredth)
