Question

(1) how many times will its surface area increase?
(ii) how many times will its volume increase?
If each edge of a cube is doubled,​

Answer 1

Answer:

1.If the edge of the cube is doubled volume of the cube is increases by 8 times. If the edge of the cube is doubled surface area of the cube increases by 4 times. If the edge of the cube is doubled volume of the cube is increases by 8 times.

2.if a cube edges are doubled , then , automatically all the six sides surfaces will be doubled in all directions , causing the cube to grow in all 3 directions. this will lead the cube volume to increase by eight times its original volume .

Answer 2

Step-by-step explanation:

Surface area of cube=6a2

Is sides of cube is doubled 

New surface area is =6×4a2

Divide 2 by 1

=24a2surfaceareaofcube1surfaceareaofcube2=6a224a2=4times

Surface area increased four times 

Volume of cube= a3 

Volume of new cube= (2a)3

=8a3

Divide 2 by 1

volumeofcubevolumeofnewcube=a38a3

Volume increased 8 times
