Ответ:
3 is the scale factor
Step-by-step explanation:
Whenever a geometrical figure is dilated by scale factor of 3, we will have perimeter to be dilated by same 3 units
Area by 3 square = 9 square units
and volume by 3 cube = 27 cubic units
Here original volume = 20
New volume = 540
Ratio = 540/20 = 27 = 3 cube
Hence scale factor is 3
