You can't. To find out a cubic capacity you need 3 measurements no just 2. Your question provides just 2 measurements.
That depends on how thick you want it. Multiply 18ft * 18ft * thickness (in units of feet). That will give you your volume in cubic feet. To convert it to cubic yards divide your answer by 27.
Either your structure has five dimensions, or else it's a bin that's 18-ft squareand 4-ft high. We'll assume the latter.Volume = (18-ft x 18-ft x 4-ft) = 1,296 cubic feet = 48 cubic yards
To convert feet to yards, you divide by 3 since there are 3 feet in a yard. So, for a box that is 55ft by 12ft by 18ft, you would multiply those dimensions together to get the volume in cubic feet. Then, divide by 27 (3^3) to convert cubic feet to cubic yards.
3 ft is equal to 1 yard, so 18/3=6yds
Capacity = 55 ft * 12 ft * 18 ft = 55/3 * 12/3 * 18/3 cubic yards = 55*4*2 = 440 cubic yards.
you just add the number of feet and leave the cubic alone. 6 ft^3+12ft^3=18ft^3
There are 1728 cubic inches in 1 cubic foot. To convert cu ft to cu in, multiply cu ft by 1728 (cu in per co ft).1,728 cubic inches per cubic foot.
To convert cubic metres to cubic feet, multiply by 35.314667 To convert cubic feet to cubic metres, multiply by 0.028316847
The volume is 55*12*18 cubic feet = 11880 cu ft.
To calculate the amount of mulch needed for a 30 ft by 18 ft area, first find the total square footage: 30 ft × 18 ft = 540 square feet. Mulch is typically sold by the cubic yard, and a depth of 3 inches (0.25 feet) is common for landscaping. To convert the area to cubic yards, use the formula: cubic yards = (square feet × depth in feet) / 27. Thus, you would need approximately 5 cubic yards of mulch for this area.
288 sq ft
You'll have to convert it to cubic inches. A cubic foot has 1 ft length, 1 ft width and 1 ft height. There are 12 inches in a foot so... 12 in x 12 in x 12 in = 1728 in^3 or 1728 cubic inches.
