The diagram shows a constant force (highlighted in red) that is applied to a box as it is dragged along the ground in a straight line from Point (a) to Point (b). What is the work done by this force between these two points? The distance between points (a) and (b) is shown in the diagram. Give your answer in units of joules to three significant figures.
