Question

what is the effect on the surface area of a cube if its edge is reduced to one third of the original​

Answer 1

Answer:

let the edge of cube be a.

so surface area= 6a^2

A.T.Q

when edge is reduced to one third, the edge =1/3a

so, surface area=6×(1/3a)^2

= 6×(1/9 a^2)

=2/3 a^2

hence the surface area will be reduced to two third of the original surface area.
