If a dinosaur was proportioned like a large iguana, we can assume that the two animals have similar body structures. Using this assumption, we can estimate the weight of the dinosaur based on its length, assuming that the weight increases as a cubic function of the length.
If a large iguana is 7 feet long and weighs 16 pounds, we can calculate the ratio of length to weight by dividing the length (in feet) by the weight (in pounds):
Ratio = Length / Weight
= 7 / 16
= 0.4375
To estimate the weight of the dinosaur, we can use this ratio and apply it to the dinosaur's length:
Weight of Dinosaur = Ratio x (Length of Dinosaur)^3
Weight of Dinosaur = 0.4375 x (25)^3
Weight of Dinosaur = 0.4375 x 15625
Weight of Dinosaur = 6835.94 pounds
Therefore, based on our estimation, a dinosaur that is 25 feet long and proportioned like a large iguana would weigh approximately 6835.94 pounds or about 3.4 tons.
