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 .
