Q. The volume of a rectangular prism is 480cm3. David measures the sides to be 6.49cm by 9.99cm by 8.41cm. In calculating the volume, what is the relative error, to the nearest hundredth.Answer:
Calculate Volume: Calculate the volume of the rectangular prism using the measured sides.Volume = Length×Width×HeightVolume = 6.49cm×9.99cm×8.41cm
Perform Multiplication: Perform the multiplication to find the calculated volume.Calculated Volume = 6.49×9.99×8.41Calculated Volume ≈54.5809×8.41Calculated Volume ≈458.903289 cm3
Find Absolute Error: Find the absolute error by subtracting the given volume from the calculated volume.Absolute Error = ∣Calculated Volume−Given Volume∣Absolute Error = ∣458.903289 cm3−480 cm3∣Absolute Error \approx ∣−21.096711 cm3∣Absolute Error \approx 21.10 \text{ cm}^3 (rounded to the nearest hundredth)
Calculate Relative Error: Calculate the relative error by dividing the absolute error by the given volume and then converting it to a percentage.Relative Error = (Absolute Error/Given Volume)×100%Relative Error = (21.10cm3/480cm3)×100%
Perform Division and Multiplication: Perform the division and multiplication to find the relative error percentage.Relative Error ≈(0.0439583333)×100%Relative Error ≈4.40% (rounded to the nearest hundredth)
