Volume is 30 x 20 x 1/6 ie 100 cu ft. 27 cu ft make one cu yd so 100/27 ie 3.7 cu yds to one significant figure.
Volume of pit = 9ft * 30ft * 2ft = 540 cubic ft = 540/27 cu yards = 20 cu yards.
v = 30 x 30x5 = 4500 cu ft
4800 cu. ft 177.78 cu yd
I have a 1.5 cu ft. Samsung and I can barely hear it.
Cubic feet of concrete required = 32 x 3 x 0.25 = 24 cu. ft 1 cu yd = 27 cu ft Answer: 24/27 cu yards = 0.89 cu yards.
72 cu yd needed
At an average of about 30 lbs per cubic foot, that is about 20/30 = 2/3 cubic feet. A little less if wet, about 1 cu ft if really dry
20 x 28 x 61 = 34160 cu. in. or 19.76852 cu. ft.
What about 30 cu.yds. of trash ??? The question does not make sense.
If the units are 30 ft x 30 ft x 4 inches, then you have 30 x 30 x 0.33 ft = 300 cubic feet300 cubic ft/27 cu yds/cu ft = 11.1 cubic yards
1.25 cubic feet, inside.
