Q. The volume of a rectangular prism is 126ft3. Bob measures the sides to be 9.48ft by 7.21ft by 1.93ft. In calculating the volume, what is the relative error, to the nearest thousandth.Answer:
Calculate Volume: Calculate the volume using the measured sides.Volume = Length×Width×HeightVolume = 9.48ft×7.21ft×1.93ft
Perform Multiplication: Perform the multiplication to find the calculated volume.Calculated Volume = 9.48×7.21×1.93Calculated Volume = 131.611044ft3
Find Absolute Error: Find the absolute error by subtracting the actual volume from the calculated volume.Absolute Error = ∣Calculated Volume−Actual Volume∣Absolute Error = ∣131.611044−126∣Absolute Error = 5.611044ft3
Calculate Relative Error: Calculate the relative error by dividing the absolute error by the actual volume.Relative Error = Actual VolumeAbsolute ErrorRelative Error = 1265.611044
Perform Division: Perform the division to find the relative error.Relative Error ≈0.0445327
Round Relative Error: Round the relative error to the nearest thousandth.Relative Error ≈0.045
