Q. The volume of a rectangular prism is 63ft3. Eric measures the sides to be 6.59ft by 3.44ft by 3.15ft. In calculating the volume, what is the relative error, to the nearest thousandth.Answer:
Calculate Estimated Volume: Calculate the estimated volume using the measurements provided by Eric.The formula for the volume of a rectangular prism is length×width×height.Estimated volume = 6.59ft×3.44ft×3.15ft
Perform Multiplication: Perform the multiplication to find the estimated volume.Estimated volume = 6.59×3.44×3.15Estimated volume ≈71.54844 ft3 (rounded to five decimal places for intermediate calculation)
Calculate Absolute Error: Calculate the absolute error by subtracting the actual volume from the estimated volume.Absolute error = ∣Estimated volume−Actual volume∣Absolute error = ∣71.54844−63∣Absolute error \approx 8.54844 \text{ ft}³ (rounded to five decimal places for intermediate calculation)
Calculate Relative Error: Calculate the relative error by dividing the absolute error by the actual volume and then converting it to a percentage.Relative error = (Absolute error/Actual volume)×100%Relative error ≈(8.54844/63)×100%
Round Relative Error: Perform the division and multiplication to find the relative error as a percentage.Relative error ≈(0.1356857143)×100%Relative error ≈13.56857143%
Round Relative Error: Perform the division and multiplication to find the relative error as a percentage.Relative error ≈(0.1356857143)×100%Relative error ≈13.56857143%Round the relative error to the nearest thousandth.Relative error ≈13.569% (rounded to three decimal places)
