It depends upon how deep you want it filled. For example, if you want it filled 6" deep, then the cubic feet would be 175 sq. ft X 0.5 ft. = 87.5 cubic feet.
87.5 cubic feet / 5 cubic feet/bag = 17.5 bags
One cubic yard of mulch will cover approximately 160 square feet at 2" deep, so you would need approximately two cubic yards of mulch to cover 271 square feet at 2" deep.
If the search area is circular, the measurement would be in square miles, not cubic miles. If this is the case, the search area would cover 785,000 square miles.
A cubic yard of stone that is 4" thick would cover 9 square yards or 81 square feet. If you need to cover 7000 sq. ft., you would need roughly 86.5 cubic yards. That's a lot of rock.
To find the volume in cubic feet needed to cover 21,000 square feet, you would also need the height of the coverage area. The volume (cubic feet) is calculated by multiplying the area (square feet) by the height (feet). Without the height, it's not possible to determine the amount of cubic feet needed to cover 21,000 square feet.
You can't convert square anything to cubic anything. If that were possible, then you'd be able to figure out how many gallons of carpet it would take to cover the floor in your room.
It would take roughly 66 bags to cover a 200 square ft area 2 inches thick
To determine the number of bags needed to cover 250 square feet at 2 cubic feet per bag, you would first calculate the total volume required: 250 sq ft * 2 ft = 500 cubic feet. Then, divide the total volume required by the volume per bag: 500 cubic feet / 2 cubic feet per bag = 250 bags needed.
To cover 300 square feet 4 inches thick, you would need approximately 3 cubic yards of gravel.
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).
A "decorative cover" would be an appropriate synonym for a duvet cover. While duvet covers are designed to keep dirt away from material, their primary function is decorative.
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.
