Question

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

Answer 1

Step-by-step explanation:

∴ the volume of cube increases by 8 times. How satisfied are you with the answer.....

Answer 2

Answer:

Surface area increases 4 times when edge is doubled. Surface area is 6x^2 if each side is x. If each side is 2x, then the SA = 6(2x)^2 =24x^2

the volume of cube increases 8 times
