1 square foot = 144 square inches
1 gallon = 231 cubic inches
Volume = (16 x 144 x 6) = 13,824 cubic inches = (13,824 / 231) = 59.844 gallons (rounded)
40 square feet * 2 inches = 40*(1/6) = 6.66... cubic ft = 41.5 UK gallons or 49.9 US gallons (approx).

4 inches = 1/3 foot so that's 6 and 2/3 cubic feet of water. - 6.6667 cu ft 1 cu ft of water = 7.482 US Gallons and 6.23 imperial Gallons so 6.6667 cu ft = 49.87 US Gallons and 41.53 imperial Gallons
A cylinder with a diameter of 19 inches and a height of 12 inches can hold up to 14.73 gallons of water.
40 square feet * 2 inches = 40*(1/6) = 6.66... cubic ft = 41.5 UK gallons or 49.9 US gallons (approx).
Here is my take: 1 gallon of water equals 231 cubic inches 1 square foot, 1 inch tall equals 144 cubic inches (12"x12"X1") 1 square foot needs 0.624 gallons to equal 1 inch of cover (144 cubic inched divided by 231 cubic inches) 16 square feet would require 9.975 gallons of water to be covered 1 inch deep. (16*0.624) **Runsky**
The height of 400 gallons of water would depend on the shape of the container. 400 US gallons has a volume of about 206,000 cubic inches, so if the inside of the container was about 59 inches square, it would also be about 59 inches high.

How many gallons of water in a 24 Round pool
Around 162,926
There are 17.66 gallons in 4,080 cubic inches of water.
It can cover 280,000 gallons of water.
One square foot is 144 square inches, so if you cover that with an inch of water you'll need 144 cubic inches. One gallon is 231 cubic inches. Dividing 231 by 144 = 0.62 gallons. So a plant growing in about 1 square foot of soil needs a bit more than half a gallon of water a week to equal 1 inch. A 4 ft x 8 ft bed = 32 sq. ft. so at 0.62 gal/sq.ft. you'd want to give it about 20 gallons of water a week.
489.76 gallons of water.
2 mi2 x 2 in = 9.293x106 ft3 = 6.951x107 gallons
Inches are a measure of length, and gallons is a measure of volume. However, volume can be measured in units of length cubed (because, for instance, the volume of a cube is the length of each side cubed).The are 231 cubic inches (or in3) per gallon.
