1 cubic foot = 7.48052 gallons (rounded)
50yd x 50yd x 9ft = 150ft x 150ft x 9ft = 202,500 cubic ft = 1,514,805 gallons (rounded)
A 4-foot column of water that is 1-foot deep would contain 4 cubic feet of water. To convert this to gallons, you would multiply by 7.48 (since 1 cubic foot is approximately 7.48 gallons). Therefore, a 4-foot column of water 1-foot deep would be approximately 29.92 gallons.
Multiply length by width by height to get volume, then convert to gallons. 216000 in cubed is 935.1 gallons
Assuming it is round, (1) convert all measurements to feet. (2) Use the formula for the volume of a cylinder to get the volume in cubic feet. (3) Convert from cubic feet to gallons. As an alternative, you can also convert all measurements to inches, and in the final step, convert from cubic inches to gallons.
398.7 gallons.
To convert cubic inches to gallons, first find the volume in cubic inches by multiplying the length, width, and height (30 x 18 x 6 = 3240 cubic inches). Then, divide the cubic inches by 231 to convert to gallons (3240 / 231 = 14.03 gallons).
300 gallons.
Multiply all three dimensions to get the volume in cubic feet. Then multiply that product by 7.48 to convert to gallons.
