What is the volume of 220 grams of an object with a density of 55/cm3

Every cm³ of that substance has 55 grams of mass
packed into it.  That's what density means.

So how many cm³ do you need in order to stuff in
220 grams ?

How many 55s make 220 ?

         220/55 = 4 .

If you have  4 cm³  of space available, you can pack
the whole 220 grams into that volume, because each cm³
will hold  55 grams, and  4 x 55 = 220 .
