3.14 x 12 x 12/4 x 30/12 cu ft x 7.5 gallons per cu ft = 2120 gallons
If you meant cu. in to cu. ft.divide by 1728.
For 1 foot deep, 400 cu ft. For 3 inches deep, 100 cu ft.
Multiply by 123 = 1728 ie 1 cu ft = 1728 cu inches.
1 cu foot = 1ft * 1 ft * 1 ft = 12 in * 12 in * 12 in = 1728 cubic inches. So 2592 cu inches = 2592/1728 = 1.5 cu ft
360 cu ft or if the "4" is inches, not feet, one twelfth of that, ie 30 cu ft
3.14 x 12 x 12/4 x 30/12 cu ft x 7.5 gallons per cu ft = 2120 gallons
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.
26 cu ft equals 44,928 cubic inches.
1.8 cubic feet = about 3,110.4 cubic inches.
12 inches = 1 ft so 30 inches = 2.5 ft
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
I think it's 34.1264 inches. Hope this helped :)
If you meant cu. in to cu. ft.divide by 1728.
54 feet 4 inches
For 1 foot deep, 400 cu ft. For 3 inches deep, 100 cu ft.
The answer depends on the thickness of the covering layer.
