Question

How does the volume of a cube change if its dimensions are doubled?

Answer 1

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 1/4 four times
