Question

THE length of each side of cube is multiplied by 3. what is the change in the volume of the cube???? please ANSWER fast

Answer 1

Answer:

IF side=x

then vol=x3

if side is 3x

then vol=27x3

27x3-x3/x3

26x3/x3

26*100

2600%

Step-by-step explanation:

Answer 2

Answer:

Let the length of each side of the cube be'l' m.

Thus the surface area = 6l^2

Now the length when made three times

L = 3l

Thus the new surface area= 6*(3l)^2= 6*9l^2

= 54 l^2

Thus the change in the surface area= 54l^2 - 6l^2 = 48l^2.
