Answer :

[tex]Work = Force \times Displacement[/tex]
[tex]Work = 15 \times 3[/tex]
[tex]Work = 45J[/tex]

The work done in pushing the box along the floor is 45 joules.

The work done is given by;

Work = distance covered × Force applied

In this particular case, we have;

Distance covered = 3 meters

Force applied = 15 newtons

So we can now substitute values into the given equation;

Work = 3 meters × 15 newtons

Work =  45 joules
