$$                    Volume/(Cube Area)=Edge/3.
$$  You MEASURE the following (..BEFORE begining the calculation):
$$  1. The volume/(SURFACE area) of the room, water A and water B.
$$  2. The iNside and OUTside temperatures of the room, and A & B.
$$  3. The SPECiFiC-heat-CAPACiTY of the iNside & OUTside AMBiENT.
$$  4. The RATE of heat-GAiN & the RATE of heat-LOSS, of the room.
$$
$$  Then with THiS you can calculate if A or B reaches 295K FiRST.
$$  [An ANSWER depends on the RATE-of-thermal-CHANGE in the room]. 
$$
