Answer:

Step-by-step explanation:
For this case we have the following value:

We can convert this first to  like this:
 like this:

Now we use the fact the the pressure is defined as  , whre P is the pressure, F the force and A the area, so then
, whre P is the pressure, F the force and A the area, so then  and then we can replace this:
 and then we can replace this:

Now from definition of work we know that  where W is the work, F the force and d the distance, so then is equivalent
 where W is the work, F the force and d the distance, so then is equivalent 
And if we replace this into the equation we got:
