Assuming you mean 90 x 90 x 20 inches, then the volume of Jello is 90 x 90 x 6 inches deep = 48600 cu in = 28.1 cu ft. At 7.48 gallons per cu ft, that is 210 gallons of jello.
The volume of the rectangle would be 16*12*34 = 6528 cubic inches. 1 cubic inch = .004 gallons so 6528 cubic inches would be .004 * 6528 = 26.112 gallons.
A cylinder with a radius of 21 inches and a height of 98 inches has a volume of 135,773.35 cubic inches. This cylinder would have a volume of 587.763 US gallons.
It depends on lots of other things, 39 inches can be any way. It is impossible to answer without more information. If you mean 39 cubic inches it would be .169 gallons.
231 cubic inches = 1 gallonVolume = 28 x 15 x 7 = 2,940 cubic inches = 12.727 gallons (rounded)
84.16 US gallons
Probably cubic inches. Gallons would be possible.
3.246753 gallons
To convert gallons to cubic inches, you would multiply by 231 (since there are 231 cubic inches in a gallon). So, 13.6 gallons would be 13.6 x 231 = 3141.6 cubic inches.
The volume of the rectangle would be 16*12*34 = 6528 cubic inches. 1 cubic inch = .004 gallons so 6528 cubic inches would be .004 * 6528 = 26.112 gallons.
1 gallon is approximately equivalent to 231 cubic inches. Therefore, 34.069 gallons would be equal to approximately 7869.339 cubic inches.
If that is 24 inches it would be 117.5 gallons
To determine the volume of the tank in gallons, you would need to multiply the dimensions (in inches) and then divide by 231 (the number of cubic inches in a gallon). Therefore, for a tank with dimensions 30x13x13 inches, the volume would be (30x13x13)/231 = approximately 27.44 gallons.
22x20x13= 5720 cu inches assuming you want in gallons it is 24.76 gallons
There would be no gallons in a 36 by 360 inch tank. It will require a third measurement to have volume.
One gallon of water is equal to approximately 231 cubic inches. Therefore, 400 gallons of water would measure approximately 92,400 cubic inches. To find the height in inches, divide the total cubic inches by the surface area of the container the water is in.
A cylinder with a radius of 21 inches and a height of 98 inches has a volume of 135,773.35 cubic inches. This cylinder would have a volume of 587.763 US gallons.
The volume is 23,430 cubic inches which would require 101.4 gallons to fill.
