Answer: 4 Step-by-step explanation: when all the lengths are multiplied by x (length scale factor), the volumes are multiplied by x³ (volume scale factor). ∴ when volume scale factor = 8 the length scale factor = ∛8 = 2 while When all the lengths are multiplied by x (length scale factor), the areas are multiplied by x² (surface area scale factor). ∴ when the length scale factor = 2 the surface area scale factor = 2² = 4
