You can't convert meters to square meters.
32.3 square feet.
As a linear meter is a length with zero width, even with an infinite number of them they will not cover an area of 30 square meters.

Square meters is AREA, it has no weight.
The side length of a square with an area of 9 square meters would be 3 meters.
A hectare is 10,000 square meters of land.
300 mm = 0.300 meters and 450 mm = 0.450 meters. Therefore, the area of each tile in square meters is 0.300 X 0.450 = 0.135 square meters. Therefore, the smallest number of tiles that can cover an area of 13 square meters is 13/0.135 or at least 97 tiles.
To cover this area you will need about 10.87 square meters of material.
Area
One cubic meter cannot be "converted" to a square measure unless we know how "deep" it is being spread. For example, if it is one meter deep, then it would cover one square meter; but if it is two meters deep, then it would cover half that area. If it were, say, 1 cm deep, then it could cover a million square centimeters (100 x 100 x 100).
