Q. The volume of a rectangular prism is 80cm3. Alex measures the sides to be 4.53cm by 2.02cm by 7.69cm. In calculating the volume, what is the relative error, to the nearest hundredth.Answer:
Given: Given:- The actual volume of the rectangular prism Vactual = 80 cm³- The measured dimensions of the prism are 4.53 cm by 2.02 cm by 7.69 cm.First, we need to calculate the volume using the measured dimensions.Vmeasured=length×width×height
Calculate volume: Calculate the measured volume:Vmeasured=4.53cm×2.02cm×7.69cmVmeasured=70.300034cm3
Calculate absolute error: Now, we find the absolute error, which is the difference between the actual volume and the measured volume. Absolute error = ∣Vactual−Vmeasured∣
Round relative error: Next, we calculate the relative error, which is the absolute error divided by the actual volume.Relative error =VactualAbsolute error
Round relative error: Next, we calculate the relative error, which is the absolute error divided by the actual volume.Relative error = VactualAbsolute errorCalculate the relative error:Relative error = 80cm39.699966cm3Relative error = 0.121249575
Round relative error: Next, we calculate the relative error, which is the absolute error divided by the actual volume.Relative error =VactualAbsolute errorCalculate the relative error:Relative error =80cm39.699966cm3Relative error =0.121249575Finally, we round the relative error to the nearest hundredth.Relative error (rounded) =0.12
