Assuming you mean the colloquial (builder's) yard for cubic yard:
36 in = 1 yd
3 ft = 1 yd
⇒ 3 ft x 3 ft = 1 yd x 1 yd
⇒ 9 sq ft = 1 sq yd
⇒ 4500 sq ft x 1 in = (4500 ÷ 9) sq yd x (1 ÷ 36) yd
= 138/9 cu yd
≈ 13.89 cu yd
230
1.85 cubic yards.
92.593 cubic yards for every inch deep.
9.26 cubic yards for every inch of depth.
To cover an area of 1 square foot with 1/2 inch of water, you would need 0.623 gallons of water.
3000 sq ft * 4 inches = 1000 cubic feet.
254 x 1/12 = 21.17 cubic feet of sand approximatelly
Volume = 900 sqft * 1/12 ft = 75 cubic feet.
One
4 square feet are needed
1 half of a inch
To determine the amount of sand needed to cover 115 sq feet 1 inch thick, you need to calculate the volume in cubic feet. Since 1 cubic foot is equal to 12x12x1 = 144 cubic inches, the volume of sand required is 115 sq feet * 1 inch / 144 = 0.7986 cubic feet.
