The microwave uses #6000 J# of energy.

Where #P# = Power, #t# = time, and #W# = work ...

#P = 1000# watts
#t = 60# seconds

The formula for Power is given by:

#P = W/t#

Therefore:

1000 Watts = #W/60#

So ...

#W=1000(60) =6000 W# (or J=Joules)

From this, we can say that a microwave oven of 1000 W uses 6000 J of energy in 1 minute (60 seconds).
