Q. The volume of a rectangular prism is 140ft3. Eric measures the sides to be 7.12ft by 3.83ft by 5.49ft. In calculating the volume, what is the relative error, to the nearest thousandth.Answer:
Calculate Volume: Calculate the volume of the rectangular prism using the given measurements.Volume = Length × Width × HeightVolume = 7.12ft ×3.83ft ×5.49ft
Perform Multiplication: Perform the multiplication to find the calculated volume.Calculated Volume = 7.12×3.83×5.49Calculated Volume ≈141.688ft3
Compare Volumes: Compare the calculated volume with the given volume to find the absolute error.Absolute Error = ∣Calculated Volume−Given Volume∣Absolute Error = ∣141.688 ft3−140 ft3∣Absolute Error \approx 1.688 \text{ ft}^3
Calculate Relative Error: Calculate the relative error by dividing the absolute error by the given volume.Relative Error = Given VolumeAbsolute ErrorRelative Error ≈140ft31.688ft3
Perform Division: Perform the division to find the relative error. Relative Error ≈0.0120571429
Round Relative Error: Round the relative error to the nearest thousandth.Relative Error ≈0.012
