Question

Find the scale factor of a cube with volume 729 ft3 to a cube with volume 2197 ft3

Answer 1

To determine the scale factor, we first get the cube roots of the volumes of the cubes.
          (Cube 1) =     729^(1/3) = 9
           (Cube 2) =    2197^(1/3) = 13
Therefore, the scale factor of these similar polygons is 9:13. 

Answer 2

Scale factor = (2197-729)/729===)Sale factor = 2.014
