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.
One cubic meter of cement at a depth of 6 inches (approximately 0.1524 meters) will cover an area of about 6.56 square meters. This is calculated by dividing the volume (1 cubic meter) by the depth in meters (0.1524), giving you the coverage area. Therefore, 1 cubic meter of cement at this depth can effectively cover a space of about 6.56 square meters.

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.

The number of bags of cement required to cover a square meter depends on the thickness of the application and the type of mix used. Generally, for a standard concrete mix, approximately 1 bag (usually 50 kg) can cover about 0.1 to 0.15 cubic meters. Therefore, for a thickness of about 10 cm, you might need around 3 to 5 bags of cement per square meter. It's best to consult specific mix design guidelines for precise calculations.
