The surface areas of similar objects are proportional to the square of their corresponding dimensions.
So if one dimension of the original is x
then the corresponding dimension of the new object is 1100% of x
= 11x
surface area of old/surface area of new = x^2/(11x^2) = 1/121
the new surface area is 121 times as large as the original
So if one dimension of the original is x
then the corresponding dimension of the new object is 1100% of x
= 11x
surface area of old/surface area of new = x^2/(11x^2) = 1/121
the new surface area is 121 times as large as the original
