5200 cubic feet
If the container is 1 inch deep, the area is 1 square foot.
That's going to depend on the shape of the container, especially on how much 'real estate' the base of the container covers. For discussion, imagine that the container is a square fish tank, and the four walls go straight up from the four sides of the square base. -- If the base of the tank covers 64 square feet and it holds 64 cubic feet, then the water in it is 1 foot deep. -- If the base of the tank covers 1 acre and it holds 64 cubic feet, then the water in it is 0.0176 inch deep. -- If the base of the tank covers 1 square inch and it holds 64 cubic feet, then the water in it is 9,216 feet (1.745 mile) deep.
There are 14.93 cubic feet in a 96-dry gallon container.
Assuming the container is full at 1500 liters, the container's volume in cubic feet will be about 53 cubic feet (52.9720005, more precisely).
500 gallons is 66.84 cubic feet.
75 US gallons of water equates to 10.03 cubic feet.
There are: 4*4*6 = 96 cubic feet
If the whole container is rectangular, then its volume is 18" x 24" x 30" = 12,960 cubic inches = 7.5 cubic feet = 56.104 gallons
3,162
The volume is 5 feet times 5 feet times 38 feet = 950 cubic feet.
55 gallons = 7.3524 cubic feet (rounded), anywhere.
