Q. The volume of a rectangular prism is 720ft3. Alex measures the sides to be 9.66ft by 9.11ft by 7.59ft. 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 measured sides.Volume = Length×Width×HeightVolume = 9.66ft×9.11ft×7.59ft
Perform Multiplication: Perform the multiplication to find the calculated volume.Calculated Volume = 9.66×9.11×7.59Calculated Volume ≈667.40334 ft3
Find Absolute Error: Find the absolute error by subtracting the given volume from the calculated volume.Absolute Error = ∣Given Volume−Calculated Volume∣Absolute Error = ∣720 ft3−667.40334 ft3∣Absolute Error \approx 52.59666 \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 ≈720ft352.59666ft3
Perform Division: Perform the division to find the relative error. Relative Error ≈0.07305
Round Relative Error: Round the relative error to the nearest thousandth.Relative Error ≈0.073
