Question

What would the surface area of a cube be if each dimension were multiplied by the scale factor 1/3? One side is 12 meters

Answer 1

the area would be (1/3)^2 of the original

Answer 2

@welshfella 1/9?

Answer 3

Yes, for example the SA for the 12m cube is

SA = 6s^2
SA = 6(12)^2
SA = 864

And if you took the side and applied the scale factor, 12*(1/3) = 4m

SA = 6s^2
SA = 6(4)^2
SA = 96

And if you found the ratio:

96:864 = 1:9 or 1/9
