Question

If each side of a cube is tripled, find the factor by which the surface area of the cube will change.

Answer 1

Answer:

9 times

Step-by-step explanation:

A cube of side length 'a' has surface area 6a^2.

Now, new side length = 3a.

Hence, new surface area is 6(3a)^2 = 9(6a^2) = 9 times of the original surface area.

Hence, your answer is 9 times.
