Final answer:
The next square number that is equal to twice thirteen is 36.
Step-by-step explanation:
To find the next square number that is equal to twice thirteen, we can start by determining the value of thirteen. Thirteen is equal to 13, so twice thirteen is 2 * 13 = 26. The next square number after 26 is 36, which is equal to 6 * 6.
Therefore, the number we are looking for is 36.
