13 1/2 sf for 2 foot deep 27 sf for 1 foot deep 54 sf for 6 inches deep 108 sf for 3 inches deep
9sq.ft.
1 cubic yard = 27 cubic feet4 inches = 1/3 footVolume = (area of the base) x (thickness)27 = (SF) x 1/3Multiply both sides by 3:81 = SF81 square feet.
One cubic yard of rock will cover an area of 81 square feet at a depth of 6 inches.
This is a nonsense question. Tons of dirt can be converted to cubic feet, depending on moisture and dirt type, but not to sf or square feet.
1032 sf = 1032/9 sq yards = 114.66... sq yards.
An acre is an area, a cubic yard is a volume, the question has no meaning
3,800 square feet at a 4-inch depth requires 46.91 cubic yards.
If you use a standard 4-inch thickness you will need a minimum of 6.17 cubic yards.
This question cannot be answered sensibly. A square foot is a measure of area, with dimensions [L2]. A cubic yard (cy) is a measure of volume, with dimensions [L3]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
The answer depends on the depth of the layer.1 yard of river rock actually means "1 cubic yard" of river rock.A cubic yard is 3 ft x 3 ft x 3 ft = 27 cubic ftIf you want a layer that is 3 ft deep, it would cover 9 square ft (i.e. 3 ft x 3 ft = 9 sq ft)If you want a layer that is 4 inches deep, it would cover 81 square ftx^2 * (4"/12") = 27x^2 = 27 * 12/4 = 81x = sqrt (81)x = 99 ft x 9ft = 81 sf
I will assume that sf is square foot. 1 yard is 3 feet long, one square yard is 3x3 or 9 square feet. Therefore 100,000 square feet divided by 9: 100,000 / 9 = 11111 yards and one square foot
