Question

Please help! Will give medal and fan!

If the length of each side of a cube is reduced to one-third its original value, is the surface area reduced to one-third its original value? Use an example to support your answer.

Answer 1

no

e.g.

let lenght of each side=9
thensurface area=9*9=81

if length reduced by 1/3 then
new lenght =3
then
surface area=3*3=9

so its not 1/3 of 81
