Hi dsjr116, Let's call Head=H, Tail=T, and Body=B Head = 6" Tail = (2 x H) + (0.5 x B) Body = H + T Therefore, Tail = 12 + 0.5B Body or B = 6 + 12 + 0.5B B - 0.5B = 6 + 12 0.5B = 18 B = 18 x 2 B = 36 Head = 6" Tail = 12 + 18 = 30" Body = 36" The alligator is 6" + 30" + 36" = 72" I hope this is helpful. If you have any questions regarding my answer please don't hesitate to ask before rating. Best regards, Rainbow
