That will depend on how thick a layer you want.
300 kilos.
assuming kilos means kilograms. In that case, there is no definite answer. Kilograms are units of mass and ite dpends on the consistency (or density) of the cement mixture. A cubic meter of cement can have various densities.

The amount of cement needed per square meter for a wall depends on the type of wall and the construction method. For a standard brick or block wall, approximately 0.1 to 0.15 cubic meters of cement mortar may be required per square meter. This translates to about 150 to 225 kg of cement, assuming a typical mix. It's essential to consider the specific design and materials used for precise calculations.

Given only the information that appears in the question you cannot. You also need to know how thick (deep) the cement needs to be.

The answer will depends on the size of the bag, how much cement it makes and the thickness of the cement layer. Since you have not bothered to share these crucial bits of information, I cannot provide a more useful answer.
