Let's do this question, two cubes have volumes in the ratio, one is to 60 for the ratio of the area
of a face of the first cube.
To that of the other is what we have, two cubes.
This is one cube.
OK, now, over here I have one more cube.
Now we need to find the ratio of this area to this area, pause the video, give it a try, and then
let's do it together.
All right, we're back.
Let's do it together.
Now, we know that volume is given by Side Cube, right?
Therefore, if it is the site of the first cube and be the site of the second cube, we have a cube
divided by cube is equal to one by sixty four.
Right now, let's take the cube root on both the sides and we get a Bybee's equal to one by four.
Right.
All right.
Now, over here, we need to find the ratio of A square by B Square.
And you can note that even if the question was asking about the total surface area also, it would have
been the same thing.
That is, even if you take six square by six B square or if you take a square by B square, the answer
will be the same.
Right.
All right.
Now we know that Ebi B is equal to one by four, therefore A square by B Square, which is what we need
to find will be equal to one by sixteen.
Right.
And that is your answer, which is option C over here.
