A pupil applies an average force of $F$ to move a box through a distance of $d$ along a horizontal table. The box has mass $m$ and the gravitational field strength is $g$. How is the work done by the pupil in pushing the box calculated?
- A$F \times d$
- B$\frac{F \times d}{g}$
- C$m \times d$
- D$m \times g \times d$
