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
3 ft is equal to 1 yard, so 18/3=6yds
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.
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
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.
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.
You can convert between feet and inches, or between cubic feet and cubic inches. You can not convert between cubic feet and inches.
First, convert the depth to inches by dividing 2 by 12 (0.1667 ft). Next, multiply 31 ft by 21 ft by 0.1667 ft to get cubic feet (108.5 cubic feet). Finally divide 108.5 cubic feet by 27 (the number of cubic feet in a cubic yard) to get your answer (4.02 cubic yards). Hope this helps!
