NONE of the choices is a correct answer.
Density is (mass) DIVIDED BY (volume).
The volume of the black cube is
2 x 2 x 2 = 8 cm^3
It's density is 48/8 = 6 gm/cm^3
The volume of the yellow cube is
3 x 3 x 3 = 27 cm^3
Its density is 135/27 = 5 gm/cm^3
The black one is denser because the RATIO of its mass to its volume is greater.
The cubes are made of different substances.
The density only depends on the substance. It doesn't matter HOW MUCH of the substance there is. It's the RATIO that counts.
The black one would be denser even if one cube or the other was the size of a supertanker.
By using Displacement method we can find volume of irregular object like marble.
<h3>What is
displacement method?</h3>
In displacement method,
First , we measuring the volume of water displaced by an object which tell us the volume of the object.
Secondly We can use the physical balance to determine its mass.
Lastly , calculate the density by dividing the mass by the volume.
Procedure to find the Volume of irregular object i.e. marble
step 1 - Fill the graduated cylinder about half full and measure the initial volume of water.
step 2 - Drop the marble in the graduated cylinder.
step 3 -Now measure the final level of water.
Step 4 - Subtract both the values.
Here , comes the Volume of Irregular Object.

Answer:
the thickness of the glass divided by thickness of water is going to be 1.333 divided by 1.52, which is 0.877. So, the height of this glass, in order to have the same number of wavelengths as in water, the height of the glass will be 0.877 times the height of the water, and so it will be smaller.
DescriptionThe Quartering Acts were two or more Acts of British Parliament requiring local governments of the American colonies to provide the British soldiers with housing and food. Each of the Quartering Acts was an amendment to the Mutiny Act and required annual renewal by Parliament.
Hope this helps
I think it is b cause I don’t think you do that
