Question

This table shows the mass and volume of four different objects. Which ranks the objects from most to least dense?
X, Y, W, Z
X, Z, Y, W
W, Y, Z, X
Z, Y, X, W

Answer 1

The answer is 

x, z, y, w

because density of each object is...

w = 0.19047619 g/cm cubed
x = 2.4 g/cm cubed
y = 0.1 g/cm cubed
z = 1.888888889 g/cm cubed

Answer 2

The correct answer is:

X, Z, Y, W

Because:

W= 0.19 g/cm3

X=2.4 g/cm3

Y= 0.67 g/cm3

Z=1.89 g/cm3

Density is the relation between the mass of a body and the volume that this body occupies

The formula would be: d=m/v

d: density

m=mass

v=volume
