You don't need to think more. Just the height of water level inscrease by
(density of water/density of ice) * original height of pool
Note-While formulating this equation the pool is regarded as rigid. So length and breadth doesn't alters.
Aluminium foil has smooth shiny surface. Due to which it reflects back the heat raditations emitted by the food stuffs upon them. Hence food remains warm for longer time.
Also i think in this case, reflection through its surface is very higher than conductance.
