How many meter in 1 kg aluminium sheet?

Well, darling, an aluminum sheet doesn't have meters, it has thickness. The density of aluminum is about 2.7 g/cm³, so a 1 kg sheet would be about 370.37 cubic centimeters in volume. If you want to know the length of a side, you'll need to know the dimensions of the sheet. Hope that clears things up for you, sugar.
