Question

The length, height, and width of a cube are multiplied by 6. What effect does this have on the surface area of the cube?

Answer 1

Answer:

Surface Area increases by 36 times.

Step-by-step explanation:

$Let \ length, \ height \ and \ width \ of \ a \ cube \ be \ a$

$Surface \ Area = 6a^2$

$Now \ length, \ height \ and \ width \ are \ multiplied \ by \ 6, that \ is \ sides = 6a$

$New \ Surface\ area = 6 (6a)^2 = 6 (36a^2) = 36 \times 6a^2$

$That \ is \ new \ surface \ area = 36 \times \ old \ surface\ area$
