Assuming a one-liter volume and a density of 1 gram per cubic centimeter for the substance, 500 microns would cover an area of 2 square meters.
To find the total area of the floor, you would multiply the length by the width. In this case, 8.4m x 10m = 84 square meters. Therefore, you would need 84 square meters to cover a floor that measures 8.4m by 10m.
