Q. The volume of a rectangular prism is 108cm3. Eric measures the sides to be 3.32cm by 4.04cm by 8.72cm. 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 measurements provided by Eric.Volume = length × width × heightVolume = 3.32cm×4.04cm×8.72cm
Perform Multiplication: Perform the multiplication to find the calculated volume.Calculated Volume = 3.32×4.04×8.72Calculated Volume = 116.905728cm3
Compare Volumes: Compare the calculated volume with the actual volume to find the absolute error.Absolute Error = ∣Actual Volume−Calculated Volume∣Absolute Error = ∣108 cm3−116.905728 cm3∣Absolute Error = ∣−8.905728 cm3∣Absolute Error = 8.905728 \text{ cm}^3
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 = (8.905728cm3/108cm3)×100%
Perform Division and Multiplication: Perform the division and multiplication to find the relative error as a percentage.Relative Error = (8.905728/108)×100%Relative Error = 0.082462% (rounded to the nearest thousandth)
