To determine the type of number that results from the product of \(\sqrt{36}\) and \(12\), let's first simplify \(\sqrt{36}\).
\[ \sqrt{36} = 6 \]
Now, we find the product:
\[ 6 \times 12 = 72 \]
Now we evaluate the type of number:
- 72 is a whole number and can also be classified as a rational number, because rational numbers include all integers (both positive and negative), fractions, and whole numbers.
Thus, the product of \(\sqrt{36}\) and \(12\) is a rational number.
So, the answer is rational.
