Q. The volume of a rectangular prism is 150cm3. Alex measures the sides to be 9.89cm by 3.43cm by 5.08cm. In calculating the volume, what is the relative error, to the nearest hundredth.Answer:
Calculate Volume: Given the volume of the rectangular prism is 150cm3, and Alex measures the sides to be 9.89cm, 3.43cm, and 5.08cm. First, we need to calculate the volume using Alex's measurements.Volume = length × width × height
Find Absolute Error: Using Alex's measurements, we calculate the volume as follows:Volume = 9.89cm×3.43cm×5.08cm
Calculate Relative Error: Perform the multiplication to find the calculated volume:Calculated Volume = 9.89×3.43×5.08Calculated Volume = 171.892524cm3
Round Relative Error: Now, we need to find the absolute error, which is the difference between the true volume and the calculated volume.Absolute Error = ∣True Volume−Calculated Volume∣
Round Relative Error: Now, we need to find the absolute error, which is the difference between the true volume and the calculated volume.Absolute Error = ∣True Volume−Calculated Volume∣Substitute the given true volume and the calculated volume into the absolute error formula:Absolute Error = ∣150 cm3−171.892524 cm3∣Absolute Error = ∣−21.892524 cm3∣Absolute Error = 21.892524 cm3
Round Relative Error: Now, we need to find the absolute error, which is the difference between the true volume and the calculated volume.Absolute Error = ∣True Volume−Calculated Volume∣Substitute the given true volume and the calculated volume into the absolute error formula:Absolute Error = ∣150 cm3−171.892524 cm3∣Absolute Error = ∣−21.892524 cm3∣Absolute Error = 21.892524 \text{ cm}^3Next, we find the relative error by dividing the absolute error by the true volume.Relative Error = \frac{\text{Absolute Error}}{\text{True Volume}}
Round Relative Error: Now, we need to find the absolute error, which is the difference between the true volume and the calculated volume.Absolute Error = ∣True Volume−Calculated Volume∣Substitute the given true volume and the calculated volume into the absolute error formula:Absolute Error = ∣150 cm3−171.892524 cm3∣Absolute Error = ∣−21.892524 cm3∣Absolute Error = 21.892524 \text{ cm}^3Next, we find the relative error by dividing the absolute error by the true volume.Relative Error = \frac{\text{Absolute Error}}{\text{True Volume}}Substitute the absolute error and the true volume into the relative error formula:Relative Error = \frac{21.892524 \text{ cm}^3}{150 \text{ cm}^3}
Round Relative Error: Now, we need to find the absolute error, which is the difference between the true volume and the calculated volume.Absolute Error = ∣True Volume−Calculated Volume∣Substitute the given true volume and the calculated volume into the absolute error formula:Absolute Error = ∣150 cm3−171.892524 cm3∣Absolute Error = ∣−21.892524 cm3∣Absolute Error = 21.892524 \text{ cm}^3Next, we find the relative error by dividing the absolute error by the true volume.Relative Error = \frac{\text{Absolute Error}}{\text{True Volume}}Substitute the absolute error and the true volume into the relative error formula:Relative Error = \frac{21.892524 \text{ cm}^3}{150 \text{ cm}^3}Perform the division to find the relative error:Relative Error = 0.14595016
