Imagine an experiment where you measure the width, length and height of a box, in centimeters. Additionally, you estimate an uncertainty (error) in each measurement. The goal is to calculate the box's volume and the propagated error in the volume. Suppose you measure the box's width, W = 17 cm, length, L = 30 cm and height, H = 11 cm. These values have errors (in centimeters) of W = 0.2, L = 0.2 and H = 0.3. Calculate the propagated error in the volume. Enter a whole number (an integer) of cubic centimeters.
