Object A has a mass of 12 g and a density of 3 g/cm3. Object B has a mass of 12 g and a density of 5 g/cm3. Which object has a greater volume and by how much?

Answer 1

Hello friend!
Here's ur answer!
Volume of Object A = 12/3 =4 cm3
Volume of object B = 12/5 = 2.4 cm3
Therefore, object a has greater volume.
4 -2.4 = 1.6 cm3.
object a has greater volume by 1.6 cm3. (Volume = mass/ density)

Answer 2

Hi friend,

Your answer:

Firstly, Volume of Object A = Mass/density
                                           = 12/3
                                           = 4 cm^3 ............1

Now,
 Volume of object B = Mass/Density
                                = 12/5
                                = 2.4 cm^3 ......................2

From 1 and 2, we can know that object A has greater volume than object B.

Difference in volume = 4 - 2.4 
                                 = 1.6 cm^3

Hence, object A has greater volume than object B by 1.6 cm^3. 

Hope it helps!
