1. Volume Scale Factor:
• The volume of statue B is 20% less than the volume of statue A.
• Volume of B = 0.8 times Volume of A.
2. Length Scale Factor:
• The volume scale factor is the cube of the length scale factor.
• k cubed equals 0.8.
• k equals the cube root of 0.8, which is approximately 0.928.
3. Surface Area Scale Factor:
• The surface area scale factor is the square of the length scale factor.
• Surface area scale factor equals (cube root of 0.8) squared, which is approximately 0.860.
4. Percentage Reduction in Surface Area:
• The surface area of statue B is the surface area scale factor times the surface area of statue A.
• Surface Area of B equals 0.860 times Surface Area of A.
• The percentage reduction k is calculated as:
• k equals (1 minus 0.860) times 100 percent.
• k equals 0.140 times 100 percent.
• k equals 14 percent.
So, the surface area of statue B is 14 percent less than the surface area of statue A.
