Q. The volume of a rectangular prism is 48cm3. David measures the sides to be 6.1cm by 3.89cm by 2.21cm. In calculating the volume, what is the relative error, to the nearest hundredth.Answer:
Calculate Volume: Calculate the volume of the rectangular prism using the given measurements.Volume = Length×Width×HeightVolume = 6.1cm×3.89cm×2.21cmVolume = 52.5609cm3
Find Absolute Error: Compare the calculated volume with the given volume to find the absolute error.Absolute error = ∣Calculated Volume−Given Volume∣Absolute error = ∣52.5609 cm3−48 cm3∣Absolute error = 4.5609 cm3
Calculate Relative Error: Calculate the relative error by dividing the absolute error by the given volume and then converting it to a percentage.Relative error = (Absolute error/Given Volume)×100%Relative error = (4.5609cm3/48cm3)×100%Relative error = 0.09501875×100%Relative error = 9.501875%
Round Relative Error: Round the relative error to the nearest hundredth.Relative error (rounded) = 9.50%
