A large slab of concrete, 5 8 0.3 m is used as a thermal storage

Question:

A large slab of concrete, 5 × 8 × 0.3 m is used as a thermal storage mass in a solar-heated house. If the slab cools overnight from 23°C to 18°C in an 18°C house, what is the net entropy change associated with this process?
