We found a huge block of ice in a water tank above English Kershope. Its depth was the bottom section of the pole so 27cm. The width is about 90cm and I estimate the length at 150cm. Volume is 364500 cubic cm or 0.36 cubic metres because 2sf is the best I can claim. Density of ice depends on temperature but at 0 oC it is 916 kg/m^3. So the mass of the block is about 300kg. Specific latent heat of fusion of ice is 336kJ/kg so it would need over 100000kJ to turn the block into water at zero Celsius and that is ignoring any energy needed to raise the temperature of the ice to zero Celsius.
