#W=2.4J#

Explanation:

The work done is the amount of energy transferred by a force. It is dependent on the force and distance that the force travelled. Therefore, work done = force x distance.
#W=fxxs#, but the distance#(s)# has to be in meters.
#40cm=0.4m# because,

#1cm=0.01m#
#40cm xx 0.01m=0.4m#

#W=6N xx 0.4m#

#=2.4J#

See the answer below...

Explanation:

We know that work done is equal to the dot product of the force and the distance covered... which we can mathematically represent as
>#W=F.S#

Here #F=6N# and #S=40/100m=0.4m#

Hence the work done is #6xx0.4# joule=#2.4# joule
