Work is given by the equation
where
is force and
is displacement.
Displacement is defined as change in position. In this case, the box moves from 5m to 20m. Its displacement is
.
The force acting on the box is the force of gravity, given as
.
Therefore, the total work done is:
(two significant figures).
