80 kilocalories. It takes 80 gram calories to melt 1 gram of ice, so it takes 80 kilocalories to melt 1 kilogram of ice.

It is a straightforward solution.
The heat of fusion of ice is calculated as Q = m Hf
where Q is the heat, m is the mass (in grams) and Hf is the heat of fusion (in grams). Look up the Hf and just multiply

you need to know the Heat of Fusion of water is 335.5, and the mass for this.
335.5kJ/kg x 1 kg = 335.5 kJ
