Question

how does the surface area of cube is changed if it's edge is doubled​

Answer 1

Answer:

Now it is given that the edge of the cube is doubled. So now the edge of the cube becomes 2a. So the new surface area (S. A1) of the cube is =6(2a)2=6(4a2)=24a2 sq.

Answer 2

Answer the are will  be reduced by 1/4 times

Step-by-step explanation:

we know that total surface area of cube = 6*(a^2)

therefore if the edge is halved

then the surface area= 6*(a/2)^2

                               = 6*[(a^2)/4]

                               =6*(a^2)*1/4 (or) [6*(a^2)]/4

therefor the area is reduced by 0ne by four times
