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.
