A study finds that the metabolic rate of mammals is proportional to m^3/4 , where m is the total body mass. By what factor does the metabolic rate of a 70.0-kg human exceed that of a 4.91-kg cat?

The mass of human is 2898 times of the mass of cat.

Explanation:

A study finds that the metabolic rate of mammals is proportional to m^3/4 i.e.

Where

k is constant

If m = 70 kg, the mass of human

If m = 4.91 kg, the mass of cat

So,

So, the mass of human is 2898 times of the mass of cat.
