They are not similar at all they are completely different. It even says it in the words
Volume of the peat moss = 
= 
Convert the above volume into 

Thus, volume in
is:
Volume of peat moss = 
= 
Now,
Total volume by using area and depth of the peat moss = 
= 
= 
Convert above values in
to get the value of volume in
:


Thus, volume in
is:
Total volume = 
= 
= 
Now, number of bags is calculated by the ratio of total volume of the peat moss to the volume of the peat moss.

Substitute the values of volume in above formula:

= 
≅
bags
Thus, number of bags of peat moss are needed to cover an area measure
by
to a depth of
are
bags.
