Question

what will happen to the area of cube of its edge is doubled ?​

Answer 1

Answer:

BELOW

Step-by-step explanation:

As we know that the cube has 6 sides and each side represents the square. Let the side length of the cube be a unit. Now it is given that the edge of the cube is doubled. ... So the new surface area of the cube is four times the old surface area.

Answer 2

Answer:

The area will increase by 4 times.

Step-by-step explanation:

Correct Question

What will happen to the area of cube if its edge is doubled?

To find

• What change will be there in area of cube if edge is doubled?

Understanding

Here the formula of TSA(Total Surface Area) is to be used to find the total area of cube if it edge is doubled. Then we have to check what is the change in the initial TSA and the final TSA.

Solution

Let the edge be l.

Initial TSA

=6l²

Final TSA

=6×(2l)²

As l = 2l given in question

=6×4l²

=24l²

Now,

Change in initial TSA and final TSA.

=24l²/6l²

=4

So the change is that the final area is 4 times of initial area.
