To determine the two consecutive whole numbers that $\sqrt{28}$ lies between, we can calculate:

1. Find the square roots of two perfect squares closest to 28:

   • $5^2 = 25$
   • $6^2 = 36$

2. Therefore, $\sqrt{28}$ lies between $\sqrt{25}$ and $\sqrt{36}$.

3. Simplifying, $\sqrt{28}$ lies between 5 and 6.

Answer: $\sqrt{28}$ is between 5 and 6.
