Answer:
Density, 

Step-by-step explanation:
Given that,
Mass of the sample, m = 55.6 grams
The sample is submerged in water and 27.3 mL of water is displaced.
We need to find the density of a sample of an small asteroid. It is equal to the mass of the object per unit volume. 
1 mL = 1 cm³
 So,

So, the density of the sample is 
.
