Final answer:
Animal B has about 2.4 x 10^-3 times more mass than Animal A.
Step-by-step explanation:
To determine the mass difference between Animal B and Animal A, we need to divide the mass of Animal B by the mass of Animal A. The mass of Animal B is approximately 8 x 6 kilograms, which can be written as 48 kilograms.
The mass of Animal A is approximately 2 x 10^4 kilograms.
Dividing the mass of Animal B by the mass of Animal A, we get 48 / (2 x 10^4) = 2.4 x 10^-3.
Therefore, Animal B has about 2.4 x 10^-3 times more mass than Animal A.
