Question

If each edge of a cube is doubled,
How many times will its surface area increase?
(0)
(ii) How many times will its volume increase ?​

Answer 1

Answer:

So the new surface area of the cube is four times the old surface area. So, the new volume of the cube is eight times the old volume.

Answer 2

Answer:

surface area is quadrupled and volume becomes 8 times

Step-by-step explanation:

if first side is a

surface area= 6a^2

volume=a^3

when side is doubled, new side is 2a

surface area= 6(2a)^2=4(6a^2)

volume= (2a)^3= 8 (a^3)
