Explanation:
This can be done by absolute dating technique. In this, the amount of radioactive material with a known half-life is measured. The measure of the radioactive decay of the elements present in the rock helps in the back calculation of the age of the rock. For older rocks, isotopes of Beryllium, Uranium, Argon etc. are used.
The white bread will mold the slowest because there is less density
So to solve this problem, we are going to have to set up a couple unit conversions and then cancel units:

This method can be used to convert between many different units and is a very helpful tool for questions such as these.
