Question

if the side of a cube is double
then total surface area become
how many times​

Answer 1

Answer:

total surface area of. cube : 6a²

when side of cube is doubled side becomes 2a

Total surface area : 6(2a)²

6(4a²)

24a²

Answer 2

Step-by-step explanation:

Let a be the side of the cube.

Then its total surface area will be S

1

=6a

2

.

Now if the sides are doubled then the length of new sides be 2a.

And the total surface area will be 6×(2a)

2

=4×6a

2

=4×S

1

.

So surface area will be four times the original surface area.
